## burble.dn42 Maintenance Log

#### 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! The [DNS Service](/home/dns) now support DNS over HTTPS.

#### 22nd June 2019

Tidied up node information.

#### 14th June 2019

A new host IRC web service has been added, based on [thelounge](https://thelounge.chat/).

See the [services](/home/burble-dn42-services) page for more details.

#### 8th June 2019

The recursive DNS service now uses parallel queries across all five regional master nodes.  
This approach takes advantage of the burble.dn42 global scale to reduce latencies, 
improve resilience and prevent local connectivity problems from impacting the results. 
See the [DNS](/home/dns) page for more info.


#### 24th May 2019

Moved and extended the DN42 monitoring so that it is more independent and also clustered.

A writeup of the hosted grafana service and monitoring is available [here](/home/grafana-services).

#### 21st May 2019

dn42-uk-lon1 is back again after being out of action for the day.

The host server apparently threw a disk after being updated to cover the MDS vulnerability and the 
provider has spent the day recovering the node.


#### 20th May 2019

Some nodes may have outages over the next few days as providers deal with the recent MDS vulnerabilities.

#### 15th May 2019

Updated my fork of [bird-lg](https://github.com/sesa-me/bird-lg) by merging [Zhaofeng](https://github.com/zhaofengli/bird-lg)'s Python2 to Python3 bird-lg updates and fixing a few outstanding problems.

The updated code is now live on the burble.dn42 [looking glass](https://lg.burble.com).


#### 13th May 2019

Moved the looking glass to its own container, in anticipation of future website changes

dn42-us-mia1 is offline again.

#### 10th May 2019

dn42-us-chi2 was suspended by the provider on 8/5 due to 'NTP reflection attacks'.

This is a hazard of running a busy NTP server as part of the [NTP Pool](https://www.ntppool.org/en/);
providers can get twitchy when they see a large amount of NTP traffic, due to the well publicised
vulnerabilities in stock NTPd.

My network uses chronyd rather than NTPd and it is simply not vulnerable to abuse in the same way
as NTPd, I also regularly monitor and check the services. On the other hand, the server does see
a large amount of NTP traffic and it can sometimes be difficult demonstrating that I'm
specifically providing a service here and not under some kind of attack.

Apologies that the server was offline for a few days, but it should now finally be back again. 

For info, here is the bandwidth graph of dn42-us-chi2 as it was suspended:

![Bandwidth Graph](markarian-bandwidth-190510.png)

It's trivial to see that an amplification attack was not occuring, as the inbound and outbound
traffic are both equal. It's a shame some providers don't consider this before suspending services,
but, understandable that the economics of providing VPS services can prohibt this.

[PLASMATRIX](https://explorer.burble.com/#/mntner/PLASMATRIX-MNT) at dn42-de-fra1

#### 5th May 2019

Added git service.  
See the [services](/home/burble-dn42-services) page for more details.`<

#### 1st May 2019

Seems traceroutes and some Europe Region, IPv4 related DNS lookups weren't working.  
Both are fixed now.

#### 30th April 2019

New node added and ready for peering

* dn42-ca-bhs2 (Beauharnois, Canada)

With the addition of several new nodes, the internal BGP confederations
have been re-orginised.  
This new organisation should provide better balance and allow for more local services.

* The North American region has been split in two, becoming Central & West Coast
and East Coast.
* lt-vil1 and at-vie1 have been moved to the East Europe region.

#### 19th April 2019

New nodes added and ready for peering.

* dn42-at-vie1 (Vienna, Austria)
* dn42-us-nyc1 (New York, United States)

#### 18th April 2019

Over the last week, and number of major changes have taken place to the burble.dn42 network.  
These include:

* Configuring [Jool](https://www.jool.mx) to provide IPv4 to IPv6 SIIT for the new 172.20.129.0/27 prefix  
The aim is for all internal services of the burble.dn42 network to be provided by IPv6, with
SIIT taking place at the network edge for external IPv4 users.
* Configuring Jool to provide a NAT64 service  
So that internal, IPv6 only, services can access external IPv4 networks
* Adding a new VXLAN to the WAN overlay  
The new VXLAN segregates DN42 traffic from the internal traffic and enables a separate DN42
routing domain. As a side effect, this change also fixes the problem where internal IP addresses were
being leaked and causing confusing traceroutes for DN42 users.

Over time, internal IPv4 services will be removed


#### 12th April 2019

New prefix 172.20.129.0/27 registered to provide space for more nodes
and additional services.

172.20.129.0/27 will be used as anycast addresses for services.
172.20.129.160/27 will be used for burble.dn42 nodes

[SIRMYSTERION](https://explorer.burble.com/#/mntner/SIRMYSTERION-MNT) at dn42-us-chi2


#### 7th April 2019

Added an old node in to the DN42 network, dn42-sg-sin2.
RPKI and DNS services have been moved to the node from dn42-sg-sin2
which should improve diversification and stability.

now participating in the DNS Anycast service.  
More details can be found on the [DNS](/home/dns) page.

[CAICAI](https://explorer.burble.com/#/mntner/CAICAI-MNT) at dn42-vn-han1

A new instance of the registry explorer has been created that references
the 'object-fix' branch of the DN42 registry. The main purpose of this
is to support the new [DNS](/home/dns) system being developed.

[http://grc.burble.dn42:8043/](http://grc.burble.dn42:8043/)

A couple of the nodes on the network experienced some downtime over the week:

* dn42-us-mia1 was down to 2 days and had to be rebuilt as my VPS provider's
storage array crashed.
* dn42-us-dal3 was also down for a few hours, the provider accidently
suspended the VPS due to a billing error on their side

#### 16th December 2018

New node !

dn42-jp-tyo1 has been commissioned and is open for new peers in Tokyo, Japan.

#### 14th December 2018

* AS4242421979/MDUCHARME at dn42-us-sea2

dn42-us-sea2 is now operational and available for peering.

#### 2nd December 2018

tinc + babeld is not a winning combination. Since introducing babeld, the burble.dn42 WAN overlay has experienced a number of periods of instability, with nodes dropping on and off the network. 

The WAN has been updated to use a Wireguard mesh with OSPF as IGP, and is now significantly more stable again. 

#### 1st December 2018

#### 30th November 2018

Three new nodes will be available for peering soon:

* dn42-us-chi2 - Chicago, United States
* dn42-us-sea2 - Seattle, United States
* dn42-us-dal3 - Dallas, United States

#### 29th November 2018

dn42-us-dal1 locked up, and has been restarted.

#### 28th November 2018

dn42-uk-lon1, dn42-lt-vil1, dn42-sg-sin1 and dn42-us-mia1 all locked up at 03:00 UTC and have now been restarted.

#### 23nd November 2018

Black Friday has delivered four new nodes to the burble.dn42 network:

* dn42-vn-han1 - Hanoi, Vietnam
* dn42-no-osl1 - Oslo, Norway
* dn42-ca-bhs1 - Beauharnois, Canada

All nodes are open to new peers, so just contact dn42@burble.com if you'd like to connect to the network.

#### 22nd November 2018

New peers added:
* AS4242420165/ZAICA at dn42-fr-rbx1
* AS42424222673/CORESTORAGE at dn42-uk-lon1

#### 18th November 2018

Updates to reverse DNS.

#### 17th November 2018

Added new peers
* AS4242423640/HESSENET at dn42-fr-rbx1
* AS4242420149/NIRF at dn42-lt-vil1

#### 17th November 2018

The internal routing protocol (IGP) for burble.dn42 has moved from OSPF to using [babeld](https://www.irif.fr/~jch/software/babel/).

All nodes on the burble.dn42 network are inter-connected with a [tinc](https://www.tinc-vpn.org/) mesh. Despite the network physically spanning across contintents, OSPF saw the tinc overlay network as being flat which prevented effective use of technologies such as anycast and forced the use of central resources. The hope is that babel, configured to use an RTT metric, will allow better use of regional services.

Please let me know if you observe any issues due to the new IGP.

#### 16th November 2018

New node in Istanbul, Turkey.

dn42-tr-ist1 has been commissioned and is now open for new peers. See the [peering](/peering) page for more details.
