Re: [Wikitech-l] Reboot of irc.wikimedia.org

Hello everyone

This has just happened. Most bots seem to have already reconnected
successfully and so has the rc-pmtpa bot. Everything seems to be in
order.

Sorry for not answering sooner, I 've just seen this.

I did not know that, but I just researched it and that is still the
case. For future reference the code in question is in
https://phabricator.wikimedia.org/source/operations-puppet/browse/production/modules/mw_rc_irc/files/udpmxircecho.py;b2d13fbc838a7f994a2e97fdffc07f15fe88bc29$49

I have no such recollection but it does make sense.

That's true. But I don't expect this to cause any kind of major
problems and experience up to now supports that. But thanks for
bringing it up. I learned something today.

Thank you for this notice.

Do you know if it's still the case that per-wiki channels on
irc.wikimedia.org are not available/able to be joined until there's
activity on that wiki? My memory is that reconnecting to irc.wikimedia.org
has not usually been the issue (as you note), but instead it's been that
there's a speaking bot account on the network that would only create a
channel after there's some activity to report about that wiki. For larger
wikis with lots of activity, this means the channels get created nearly
instantly after a server restart. For smaller wikis with little activity,
this means that the channels may not get re-created for days or even weeks.

I just tested irc.wikimedia.org again and it appears that joining/creating
arbitrary channels is not allowed. This makes me think that bot accounts
and others would be disallowed from joining small/quiet wiki channels
until those channels are re-created by by the server/rc-pmtpa, unless some
kind of whitelist or workaround has been implemented.

[Wikitech-l] Reboot of irc.wikimedia.org

[Alexandros Kosiaris]

Hello everyone,

This is to inform you that on Monday Feb 22nd 2018 ~10:00 UTC, the
infrastructure powering irc.wikimedia.org will be rebooted for
security upgrades. This is expected to only impact bots that are using
irc.wikimedia.org AND are not able to automatically reconnect on
connection failure. From recent experience (the equipment was rebooted
210 ago last time, with no fallout) those are very limited in number
these days.

Regards,
