Sorry for cross-posting!

Reminder: Technical Advice IRC meeting again **tomorrow, Wednesday 3-4 pm

The Technical Advice IRC meeting is open for all volunteer developers,
topics and questions. This can be anything from "how to get started" over
"who would be the best contact for X" to specific questions on your project.

If you know already what you would like to discuss or ask, please add your
topic to the next meeting: https://www.mediawiki.org/

Hope to see you there!

Re: [Cloud] [Cloud-announce] ToolsDB maintenance

[Brooke Storm]

Maintenance is finished on ToolsDB.  Things should be stable from here in, but 
some tools might need a restart to reconnect.

[Cloud] [Cloud-announce] prometheus user issue

[Arturo Borrero Gonzalez]

Hi!

We deleted the prometheus user from LDAP and created it locally [0].

This may cause puppet failures, since there is a timeframe in which the
id/gid in /var/lib/prometheus is the old LDAP one.

We are running a massive, CloudVPS-wide deluser/adduser/chown operation
to fix this.

Re: [Cloud] [Cloud-announce] Rolling VM reboots next Wednesday, 2018-06-06, beginning at 14:00 UTC

[Andrew Bogott]

Reminder:  These reboots will start in about 12 hours.

As part of routine security maintenance, we'll be rebooting all VMs 
and virtualization hosts next Wednesday starting at 14:00 UTC (7AM San 
Francisco time).


Toolforge users should be largely unaffected by this activity. Other 
projects (including deployment-prep) will experience sporadic 
downtime, a few minutes for each interruption.


The entire process will take several hours.  If you need a 
to-the-minute advance schedule for any particular reboot, please let 
me know and I'll put your system at the start.
