thyestes upgrade

1518: I'm in the middle of the thyestes upgrade, and running into some problems, I think with systemd configuration causing it to reboot before bringing up the network interface. I have a network serial console so currently assuming I can fix this via systemd rescue (or, worst case, emergency) without requiring a manual intervention from the hosting company, which would of course take much longer.

1620: somewhat struggling with the OVH rescue options right now, because their rescue system boots with a French keyboard and also the root password for the rescue system isn't coming through to gmail for some reason. I did get thyestes to boot once or twice, suggesting that something weird is going on with systemd (what a surprise), but I'm hopeful I can reboot it now into systemd rescue and maybe figure out what's going on. (Remembering to disable OVH monitoring so it won't auto-reboot the machine should help.)

1706: turns out the entire problem was that systemd runs very very slowly if you put the kernel console parameters in a particular order (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763601). Changing that fixes it. I'm going to delay the upgrade again, but try to complete the network interface renaming to consistent names today.

I may have said that too soon…

Good news though, atreus was completely fine when I was able to get through to it. Happily backing things up, flushing out its disk cache. You know. Computer things.

Routing issues resolved

We seem to be good, people.

ISP routing issues

atreus is currently unreachable at least for me, I believe due to planned maintenance on our ISP's routers which seems to be causing more significant problems than they previously anticipated. The maintenance window is planned to close midnight UK time (2014-05-08T23:00Z), so hopefully things will be back to normal by that point.

Atreus key fingerprints

Following Heartbleed, I've replaced the IMAP and SMTP certificates used on atreus. From now on it seems sensible to publish the fingerprints in a verifiable fashion. The key used to sign the statement below is on various keyservers; you should use normal PGP / WoT approaches to verify. (Ideally by finding me in person and verifying my identity.)

atreus running again

For unknown reasons the first power cycle did nothing, ie left it down. Second one today fixed that. There are a few things I'm trying to improve uptime; there may be further downtime if I need to do anything drastic, but hopefully things will be better overall.

Unscheduled downtime

atreus is down again, suggesting a hardware problem. The ISP should reboot it fairly promptly, and I'll investigate further to try to figure out what's causing this :-(
