Prechecks look good. We did most networking and DNS changes that could
be done before the big switch. We hope the migration/downtime will be
limited to 16:00-20:00 UTC today (date -d "Fri 28 Nov 2025 16:00 UTC").

One thing we didn't manage to get in place is IPv6. After the
migration the services will only be accessible through IPv4. We hope
to get IPv6 access back at a later time.

https://forge.sourceware.org will not be affected by this, so this
might be an ideal time to play with it if you haven't yet. See
https://gcc.gnu.org/wiki/ForgeExperiment Make sure to register with
your @gcc.gnu.org/@sourceware.org account/email first though, because
email and wiki will not work during the downtime.

This is part of a larger effort to upgrade the Sourceware hardware,
services and isolation. The Sourceware Project Leadership Committee,
overseers, Software Freedom Conservancy, FSF sysadmins, Red Hat IT
(https://osci.io) and OSUOSL work closely together as discussed during
the last https://sourceware.org/sourceware-wiki/OpenHouse2025/

The Software Freedom Conservancy, our fiscal sponsor, is holding a
fundraiser match challenge. To keep Sourceware worry-free, friendly
and independent one of the best things you can do is become an SFC
Sustainer https://sfconservancy.org/sustainer/
Your support currently counts double!
