037 2023.01.29 23:10 - 2023.01.30 17:00 (ADP) | unstable ethernet link to tent-3
--------------------------------------------------------------------------------
**impact**:
very unstable uplink for ap in `tent-3`
**hotfix**:
shutdown ap via poe to move clients onto other accesspoint (there really are no other ap in this tent though :()
**problem**:
someone butchered the ethernet cables (from the network core) by squeezing and bending them through cable guides.
**fix**:
Tried "unbending" them and the link came back!

039 2023.02.07 (ADP) | unstable ethernet link in tent-3 (again)
---------------------------------------------------------------
**introduction**:
the uplink for `tent-3` went flacky again
**problem**:
the cables took irrepearable damage from mishandling (see `incident 035` for details)
**fix**:
* install new access switch into `tent-2` (`sw-access04`: `220bb14`)
* migrate uplink for `tent-3` from the `core` onto `sw-access04`
040 2023.02.28 08:00 (ADP) | dns issues
---------------------------------------
**introduction**:
Someone on site called and notified me that "the internet is not working".
**problem**:
`gw-core01` stopped serving dns queries:
```
root@gw-core01:~# logread | grep max
Tue Feb 28 08:44:16 2023 daemon.warn dnsmasq[1]: Maximum number of concurrent DNS queries reached (max: 150)
```
**fix**:
* increased `maxdnsqueries`
* increased `dnscache`
* changed upstream dns to `9.9.9.9` (quad9) and `1.1.1.1` (cloudflare)
see `a236643` for details
