## 4th January 2021
|
|
|
|
Happy New Year DN42.
|
|
|
|
#### New Website
|
|
|
|
The new year brings a new website for burble.dn42 built using [Hugo](https://gohugo.io/) and statically
|
|
delivered from each core node for speed. As always, the source for the website is available in the
|
|
[gitea repo](https://git.burble.dn42/burble.dn42/www).
|
|
|
|
#### Anycast MTU
|
|
|
|
The MTU for anycast services has been reduced to 1280 after a problem was seen with IPv6 path MTU discovery.
|
|
|
|
The problem was due to an asymmetric path, where a request to the wiki went to one node but the return
|
|
path was via a different node. The other node also hosted a wiki instance, which meant that pmtud ICMP
|
|
messages on the return path were being picked up by the wrong node. To fix this, the MTU has been clamped
|
|
to the minimum allowable size of 1280.
|
|
|
|
Interestingly, Cloudflare also recognised the same type of issue and wrote up what they did in their [blog](https://blog.cloudflare.com/increasing-ipv6-mtu/).
|
|
|
|
The following services were impacted by the changes.
|
|
|
|
- DNS Services
|
|
- NGINX Reverse Proxy (and therefore also all websites, including the Wiki mirrors)
|
|
- WHOIS Service
|
|
|
|
|
|
#### New Nodes
|
|
|
|
es-mad1 in Madrid, Spain has already been delivered and is now open for peerings.
|
|
|
|
The new node in Hong Kong, hk-hkg1 has also been delivered and I'm now just waiting for IPv6 to be available
|
|
before it too will also be ready for peering.
