The encryption keys and tunnel addresses should not need -to change. - - -#### 4th May 2020 - -Several of the burble.dn42 core nodes have been upgraded to Ubuntu 20.04. This required -a short outage, but will allow for a refactoring of a few services in the future. - - -#### 13th April 2020 - -Bugs have been fixed and both instances of the burble.dn42 website are now running -in a new environment with the latest grav. - -The new website instance is the first burble.dn42 application running on Ubuntu 20.04 -(Focal Fossa). - -#### 11th April 2020 - -The clearnet version of this [website](https://dn42.burble.com) is running with -a new instance that has the latest grav. -Please let me know if you spot any problems. - -The DN42 instance continues to run with the previous version. - -#### 4th April 2020 - -Well, that was fun; burble.dn42 had a number of outages over this evening, caused by trying -to perform a rolling upgrade across the network. The biggest of these took out the burble.dn42 -DNS service for an extended period, impacting DNS resolution across DN42. - -The plan had been to perform a full upgrade and reboot for every burble.dn42 node. To minimise -disruption I perform updates across groups of servers that are chosen to be independent -so that service resilience should not be impacted. -However, this time there were two key failures: - -- The provider configuration for ca-bhs2 meant that it could not mount all of its disks when -rebooted and it ended up in maintenance mode. The server needed to be recovered via the -IPMI console. Whilst global services continued to be provided by other nodes, peers on -ca-bhs2 lost connectivity whilst the node was recovered. - -- The new pdns-recursor that was implemented at the end of March (see below) had a different -runtime path than the default OS install. This meant that when each of the core nodes was -restarted the pdns-recursor failed to restart as the runtime path was missing. Since the DNS -service is resilient, it continued to operate without problems until the last core node was -restarted, at which point the entire service failed. Without DNS, most of the remaining -burble.dn42 failed or could not be restarted and recovery was also hampered by having to -work without having DNS available. - -#### 1st April 2020 - -at-vie1 will be decommissioned by 14th April. -If you are peered on this node, please contact me to move the peering to another node. - -#### 28th March 2020 - -The patched pdns recursor is now deployed to all core nodes. - -Please let me know immediately if you notice odd DNS behaviour. - - -#### 24th March 2020 - -fr-sbg1 (which hosts the europe region core DNS service) is currently testing a special pdns -recursor build in order to try and fix [this issue](https://github.com/PowerDNS/pdns/issues/8106). - -The server is likely to be used for most recursive DNS lookups across Europe that use the -new DNS anycast addresses, or my service directly. Please let me know immediately if you -notice odd DNS behaviour. - - -#### 26th January 2019 - -This weekend has been a huge maintenance weekend for burble.dn42, with the following -updates taking place: - -- A number of nodes have been built and swapped in to the network to upgrade and manage renewals - -||| -|---|---| -| fr-rbx1 replaced by fr-rbx2 | *fr-rbx2 was a much faster node* | -| ca-bhs2 replaced with a new node | *the replacement is also much faster* | -| us-dal3 replaced by us-dal1 | *us-dal3 was a poor performer and has been replaced with a dedicated server* | -| au-syd1 replaced with a new node | *memory increased from 1G to 2G* | -| sg-sin2 replaced with a new node | *memory increased from 1G to 2G* | -
-Node renewals are now mostly sorted until November, which will be a nice break for my wallet. - -- The build of ca-bhs2 introduced a new disk layout for my core nodes, which is intended -to provide more flexibility for new features. uk-lon3, a private storage -node, was also rebuilt for the new design. - -A bad decision around backups meant that I also had to re-create all the services on -fr-rbx2 and us-dal1 as they were swapped in to their new roles. As a result, the services -on these boxes were also flattened and rebuilt to the new disk layout. - -At some future point, fr-sbg1 will follow and also change to the new layout. - -- The burble.dn42 is organised around a core network of servers in each region, the updates -this weekend complete a series of changes to upgrade the core nodes that has been taking -place since November 2019. A lot of the recent work has been to update the services so they -are on, or point to, the new core nodes. - -The core network looked like this prior to November 2019: - -|Name|CPU|Memory|Disk|Network|Descr| -|---|---| -| fr-rbx1 | i5-2400 (4/8 x 3.4Ghz) | 16G | 2TB Consumer HDD | 100mbps un-metered | Kimsufi KS-10 | -| ca-bhs2 | i5-3570S (4/8 x 3.8Ghz) | 16G | 2TB Consumer HDD | 100mbps un-metered | Kimsufi KS-10 | -| sg-sin2 | virtual (1 x 3.5Ghz) | 1G | 30GB HDD | 1TB @ 1gbit | OVH VPS | -| us-dal3 | virtual (2 x 3.4Ghz) | 5G | 120GB HDD | 5TB @ 10gbit | HostDoc VPS | -
- -Following the upgrades, the core now consists of the following servers: - -|Name|CPU|Memory|Disk|Network|Descr| -|---|---| -| fr-sbg1 | E5-1620 (4/8 x 3.7Ghz) | 32G | 3 x 480GB SSD | 500mbps un-metered | OVH SYS | -| fr-rbx1 | E3-1245 (4/8 x 3.4Ghz) | 32G | 2 x 480GB SSD | 500mbps un-metered | OVH SYS | -| uk-lon3 | virtual (2 x 3Ghz) | 3G | 3TB HDD | 10TB @ 1gbit | HostHatch | -| ca-bhs2 | E5-1620 (4/8 x 3.7Ghz) | 32G | 2 x 2TB Ent. HDD | 500mbps un-metered | OVH SYS | -| us-dal3 | C2750 (8 x 2.4Ghz) | 8G | 240GB SSD | 100mbps un-metered | drserver | -| sg-sin1 | virtual (4 x 2.2Ghz) | 4G | 24GB SSD | 1gbit un-metered | ITLDC VPS | -
- -#### 31st December 2019 - -The Christmas period has been a really busy period for burble.dn42, with integration -and transfer of services over to the new nodes. Primarily, this has meant moving services -from fr-rbx1 and sg-sin2 to fr-rbx2, fr-sbg1 and sg-sin1. As part of the rebuilding, -I've also taken the opportunity to re-create most of my ansible scripting, with the -intent that this will eventually be published. - -Most services are now moved, with the main exception of DNS and the GRC, both of which -need more significant work. The website also now needs major updates to reflect the -changes I've made. - -The following new nodes are also open for peering: - - - dn42-fr-rbx2 - - dn42-fr-sbg1 - - dn42-ch-zur1 - - dn42-sg-sin1 - - dn42-hk-hkg1 - -**Happy New Year** - - -#### 24th December 2019 - -The last month has been spent redesigning my WAN and introducting a latency based metric for -connectivity between nodes. This is now mostly complete, but not without its own follow on -problems that need to be resolved. - -Things still to do include: - - Fixing the service delivery layer as a software upgrade breaks IPv6 connectivity - - Adding documentation to the website on the new design - - Opening new nodes for peering - - Making the config public - -Another new node will also be added, dn42-fr-rbx2 and dn42-fr-rbx1 will be retired. - -**Merry Christmas DN42** - -#### 29th November 2019 - -Black friday is here and new nodes are on the way. - -* dn42-fr-sbg1 -* dn42-ch-zur1 -* dn42-sg-sin1 -* dn42-hk-hkg1 - -#### 2nd November 2019 - -Retired dn42-us-lax2, dn42-us-chi2, dn42-ca-bhs1, dn42-tr-ist1 and dn42-no-osl1. -Restructured the internal confederations. - -#### 26th October 2019 - -New experimental node added hosted in the Oracle Cloud environment in Mumbai, India. - -Users are welcome to peer and test the node, but should be aware there may be short notice changes -or interruptions to service. - -#### 19th October 2019 - -After a few weeks of outage and putting up with influx using up a vast amount of resources, the monitoring -service has finally moved to a federated prometheus architecture. Hopefully this will have better -performance than the influx architecture used previously. At some point I'll update the monitoring page with -details of the new configuration. - -#### 12th October 2019 - -The burble.dn42 wiki service is now part of the global anycast for wiki.dn42. - -See the [services](/home/burble-dn42-services) page for more details. - -#### 2nd October 2019 - -The recursive DNS service now supports clearnet queries - -#### 15th September 2019 - -Stop supporting IPsec tunnels - -#### 21st August 2019 - -Removed sg-sin3 and vn-han1 - -#### 13th August 2019 - -Added DN42 wiki service [editable via dn42](https://wiki.burble.dn42), -[readonly via clearnet](https://dn42.dev). - -Issued new Certificate Authority root certificate with a longer expiry date. - -#### 11th August 2019 - -Added a couple of Python 3 updates for [bird-lg](https://github.com/sesa-me/bird-lg) that fixes -broken BGP map functionality in the [looking glass](https://lg.burble.com/). - -Influx ate all the memory (10gb!) on de-fra1, so is currently offline until it can be fixed. - -#### 28th July 2019 - -Add dn42-us-mia2, which will replace dn42-us-mia1 - -#### 25th July 2019 - -Add pingable.burble.dn42 - -#### 21st July 2019 - -Decommissioning of dn42-ru-mos1 and dn42-us-sea1 - -#### 17th July 2019 - -DoH!

A description of the network is available in the -[about](/about) page. - -burble.dn42 is a large network and there are some restrictions in place to protect both -this network and the rest of the DN42 network. -Please ensure you read the information below before requesting to peer. - -####Peering Requests - -Please mail **dn42@burble.com** if you'd like to peer with me. - -**Peering Requirements** - -To peer with burble.dn42, you must meet the following requirements: - -* You must have at least **two** peerings already established with other DN42 networks - - *Sorry, but burble.dn42 is not open to new starters. If you are a new starter in DN42 - please use the [peerfinder](https://dn42.us/peers) or ask on [IRC](https://dn42.dev/services/IRC); - there are lots of other networks who will be happy to peer with you, and some even offer automatic - peering. - This is a tough restriction, but one that is in place to promote network diversity.* - -* You must support IPv6 -* You must implement ROA checks - -* Contact information in the registry must always be up to date and admins must repond when contacted - - *Contacts must also be reachable in case of problems. In addition, the network is ever - evolving and failure to respond to change notices may result in your peering being suspended.* - -At a minimum, I'll need to know the following in order to establish a peering: - -* The burble.dn42 node you would like to peer with -* Your ASN -* The public address of your host -* The tunnel parameters, e.g. - * Port number, if using wireguard or OpenVPN - * Public key for wireguard - * Any special config you need that is different to my defaults -* IP addresses of your end of the tunnel - * Typically these will be a single IPv4/32 and IPv6/128 from your DN42 allocation -

- -All peerings will be configured as a full transit session. - -#### Residential ISPs and Dynamic IP addresses - -A 24/7 connection, with static IP addresses are the norm for DN42. If you are connecting from a -residential ISP or otherwise have a dynamic IP please let me know so that I can configure my side -appropriately. If you don't do tell me, the peering will stop working when your IP address changes. - -#### Supported Tunnel Types - -I prefer to use [wireguard](https://wireguard.io/), it's simple to set up and just works. -I also support OpenVPN tunnels. - -* **[Wireguard](https://wireguard.io/)** - - I use a random port number and unique key for each Wireguard peer, so mail me to confirm - the port number and public key. - Endpoint names and IP addresses are detailed below. - - My wireguard AllowedIPs are: - ``` -AllowedIPs=fe80::/64 -AllowedIPs=fd00::/8 -AllowedIPs=0.0.0.0/0 - ``` - - Note that wg-quick does not support adding a peer address. If you want to use wg-quick you will - need to delete and re-add the wireguard interface IP address and configure it as a point to point - address or you will run in to next-hop problems when using BGP. See the - [DN42 Wiki](https://dn42.dev/howto/wireguard) on how to use iproute2 to configure a point to point - address. - -* **[OpenVPN](https://openvpn.net/)** - - By default I will configure the following OpenVPN parameters, with a random OpenVPN port number - and shared key. - - ``` -comp-lzo -cipher aes-256-cbc -auth sha256 - ``` - -####Allowed Traffic - -Only the network ranges will be forwarded through the DN42 network, all other traffic will be dropped. - -**IPv4** -``` -172.16.0.0/12 -10.0.0.0/8 -``` - -**IPv6** -``` -fd00::/8 -``` - -BGP peer addresses are more permissive to allow for link local or non-DN42 IP addresses within the -tunnel, but these will not be forwarded through the DN42 network. - -##### Flow Control and BGP Rate Limiting - -A typical BGP session in DN42 will use a trivial amount of traffic. However, for large networks like -burble.dn42 some transient events, such as BGP flapping, can generate multi MB/sec traffic flows that -damange the network and create instability across DN42. - -To protect the network from misconfigurations and prevent excessive updates from being propagated to the -rest of DN42, the burble.dn42 network implements rate limiting on direct BGP sessions. The rate limiting -activates when a large amount of BGP traffic is seen (typically 10's or 100's of thousands of -updates a second) over a sustained period and will typically reset automatically within an hour. - -There are no other controls applied to transit or non-BGP traffic. - -#### BGP Configuration - -||| -|---|---| -|**Network Name** |BURBLE| -|**BURBLE-MNT**|dn42@burble.com| -|**ASN**|AS4242422601| -  - -The burble.dn42 network uses a custom build of -[bird 2](https://bird.network.cz/?get_doc&f=bird.html&v=20), and the -following features are supported: - -* Multiprotocol BGP [RFC 4760](https://www.rfc-editor.org/info/rfc4760) -* BGP Large Communities [RFC 8092](http://www.rfc-editor.org/info/rfc8092) -* BGP Confederations [RFC 5065](https://www.rfc-editor.org/info/rfc5065) -* DN42 Route Origin Authorisation (ROA - see below section on Route Filtering) -* DN42 [BGP communities](https://wiki.dn42.us/howto/Bird-communities) -* burble.dn42 custom [large communities](/home/bgp-communities) -* burble.dn42 [Routing Policy](/home/routing-policy) - -The source code for the custom bird used on the network is available on -[git.burble.dn42](https://git.burble.dn42/burble.dn42/bird) - -**Route Filtering** - -The network applies strict Route Origin Authorisation (ROA) filtering to all -received and exported routes.

The biggest of these took out the burble.dn42 +DNS service for an extended period, impacting DNS resolution across DN42. + +The plan had been to perform a full upgrade and reboot for every burble.dn42 node. To minimise +disruption I perform updates across groups of servers that are chosen to be independent +so that service resilience should not be impacted. +However, this time there were two key failures: + +- The provider configuration for ca-bhs2 meant that it could not mount all of its disks when +rebooted and it ended up in maintenance mode. The server needed to be recovered via the +IPMI console. Whilst global services continued to be provided by other nodes, peers on +ca-bhs2 lost connectivity whilst the node was recovered. + +- The new pdns-recursor that was implemented at the end of March (see below) had a different +runtime path than the default OS install. This meant that when each of the core nodes was +restarted the pdns-recursor failed to restart as the runtime path was missing. Since the DNS +service is resilient, it continued to operate without problems until the last core node was +restarted, at which point the entire service failed. Without DNS, most of the remaining +burble.dn42 failed or could not be restarted and recovery was also hampered by having to +work without having DNS available. + +#### 1st April 2020 + +at-vie1 will be decommissioned by 14th April. +If you are peered on this node, please contact me to move the peering to another node. + +#### 28th March 2020 + +The patched pdns recursor is now deployed to all core nodes. + +Please let me know immediately if you notice odd DNS behaviour. + + +#### 24th March 2020 + +fr-sbg1 (which hosts the europe region core DNS service) is currently testing a special pdns +recursor build in order to try and fix [this issue](https://github.com/PowerDNS/pdns/issues/8106). + +The server is likely to be used for most recursive DNS lookups across Europe that use the +new DNS anycast addresses, or my service directly.

It is intentionally designed as a fast and lean theme and may not fit the requirements of complex projects. If a more feature-complete theme is required there are a lot of got alternatives out there. You can find a demo and the full documentation at [https://geekdocs.de](https://geekdocs.de). + +![Desktop and mobile preview](https://github.com/thegeeklab/hugo-geekdoc/blob/master/images/readme.png) + +## Build and release process + +This theme is subject to a CI driven build and release process common for software development. During the release build, all necessary assets are automatically built by [gulp](https://gulpjs.com/) and bundled in a release tarball. You can download the latest release from the GitHub [release page](https://github.com/thegeeklab/hugo-geekdoc/releases). + +Due to the fact that `gulp` is used as pre-processor the theme cannot be used from the master branch by default. If you want to use the theme from a cloned branch instead of a release tarball you'll need to install `gulp` locally and run the default pipeline once to create all required assets. + +```Shell +# install required packages from package.json +npm install + +# run gulp pipeline to build required assets +gulp default +``` + +See the [Getting Started Guide](https://geekdocs.de/usage/getting_started/) for details about the different setup options. + +## Contributors + +Special thanks goes to all [contributors](https://github.com/thegeeklab/hugo-geekdoc/graphs/contributors). + +Geekdoc is inspired and partially based on the [hugo-book](https://github.com/alex-shpak/hugo-book) theme, thanks
