The WMF’s technology department has for this quarter the goal of testing and
temporarily switching the main operational data centre from Eqiad (located
in Chicago) to Codfw (located in Dallas)~[1,2]. This includes both
back-end-processing as well as serving live traffic from it.
As a part of this effort, we are scheduling a switch-over for RESTBase and
its back-end services, including: Parsoid, the Mobile Content Service,
CXServer, Mathoid, Citoid, Apertium and Zotero~. Technically, it will not
be a real switch-over per se, because we will keep all of those services
active in both DCs. However, external traffic will be directed to the Dallas
Hi all, just a quick heads-up:
given the small issues we experienced last time, which we've found to
be unrelated to the switch itself, we scheduled a new switch-over test
lasting 24 hours, which is scheduled to start tomorrow (April 5th) at
14:00 UTC. We don't expect any significant user impact.
Anyways, should you have any questions or concerns, don’t hesitate to
contact us here
or on IRC (#wikimedia-services / #wikimedia-operations @ freenode).
