Hey all,
another round of the Technical Advice IRC meeting is taking place on
**Wednesday, Oct 10, 3-4 pm UTC** on #wikimedia-tech.
This week's meeting will be hosted by @Amir1 and @CFisch_WMDE - Question
are welcome in English, Persian & German :-)
The Technical Advice IRC Meeting is a weekly support event for volunteer
developers. Every Wednesday, two full-time developers are available to help
you with all your questions about Mediawiki, gadgets, tools and more! 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:

Due to production optimization, the following wikis have been moved on
eqiad datacenter (the one where wikireplicas[0] live) from s3 to s5:
cebwiki
enwikivoyage
mgwiktionary
shwiki
srwiki
s3 will still contain the other 900+ wikis and s5 will still contain
dewiki, with no further changes.
This means you will have to use s5.labsdb instead of s3.labsdb to access
the 5 wikis above. No change will be needed if you use wiki-specific
endpoints (e.g. shwiki.analytics.svc.eqiad.wmflabs). This is unlikely to
create any issues because both of the 2 endpoints above point to the same
proxy and database servers. The meta_p database, which is the canonical
place to check that information has been updated accordingly (so tools like
[1] caught it with no change needed). The proxy change will be deployed
next week.
A reminder that even if that means no changes are technically needed
because accessing s3.labsdb will also give you access to s5 data and
vice-versa, please remember we don't discard in the future having different
proxies and servers for different slices of data due to not being
physically able to store all data from wikis in a single server for the
wikireplica service.
If someone is curious why the movement, those 5 wikis total 500-1TB of data
on production, so we needed to move them to servers with more available
disk [2]. The change on production will take effect after the switchback
datacenter.
Thank you for your understanding,

Routine network upgrades are scheduled for Thursday which may result in
brief WMCS service interruptions. In particular, Wikitech and Horizon
may stop working, and instance creation/deletion/updating may briefly fail.
The network engineers have reserved a two-hour window beginning at 16:00
UTC (9 AM Pacific time). Their worst case scenario is 30 minutes of
downtime but if all goes well the interruption should not be noticeable,
just the time to unplug a cable from one switch and plug it into another.
