## burble.dn42 Maintenance Log
#### 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.
