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 o
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.
