Sourceware service migration; downtime friday/weekend 28/29/30 nov

Various sourceware.org, cygwin.com, gcc.gnu.org, dwarfstd.org,
elfutils.org and valgrind.org services will migrate to a bigger server
in a new datacenter this Friday afternoon.

We already did a test migration and theoretically a fresh data sync to
the new datacenter should take just ~4 hours. But there are also
various DNS updates that need to be coordinated and might take some
time to propagate. So expect some service interruptions starting
Friday afternoon possibily extending into the weekend.

Please follow https://fosstodon.org/@sourceware for updates.

For more background about bigger servers, datacenter moves and
(upcoming) service isolation see

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!
