Hi there!
Next Monday 2019-10-28 @ 14:30 UTC we will do a maintenance operation on
Toolforge which consists in rebuilding the main front proxy [0] used to
serve
webservices. We expect this to be done within a 30 minutes window.
The operation consists on replacing the old virtual machines supporting the
proxy (currently running Debian Jessie) with more modern instances running
Debian Buster. Both Grid/Kubernetes backends are affected by this change.
We
don't expect a lot of service downtime, but there is a key point in the
operation which is migrating data stored in Redis which can be tricky. The

Examples of things affected by this change:
* Browsing Toolforge webservices
* Browsing to
https://tools.wmflabs.org/<toolname>
* Browsing to
https://tools.wmflabs.org/admin/ (Toolforge landing page)
* Browsing PAWS (to some extent, since it shares part of the toolforge
proxy)
Example of things not affected by this change:
* webservices backend operations
* SSH bastions
* grid queues, grid jobs
* wiki-replicas, toolsdb
* other CloudVPS projects
regards.
