[SAC] [Hosting] MAINTENANCE: Network Uplink migration to LinkOregon - Tuesday, Sep 6 2200 UTC

[Lance Albertson]

All,

I have an update on some issues we did discover after the fact. For
now, everything with IPv4 seems to be 100% OK. Please let me know if
that isn't the case.

We did however have SLAAC enabled for a while on the other subnets
where we normally didn't have it enabled. So if you see an IPv6
address that is automatically assigned but it's not routable, that
would be the case.

HOWEVER, we are having some very strange issues with IPv6 on _some_ of
the subnets. We weren't able to track down the root cause today and
will try tomorrow.

As of right now, it seems that this is only happening on the following
IPv6 subnets:

2605:bc80:3010:200::/64 (Gentoo)
2605:bc80:3010:400::/64 (Drupal)
2605:bc80:3010:401::/64 (Drupal Virt)
2605:bc80:3010:600::/64 (Fedora)
2605:bc80:3010:700::/64 (OSM)
2605:bc80:3010:a00::/64 (Buildbot/RTEMS)
2605:bc80:3010:b00::/64 (Debian)

If I am missing any IPv6 subnet that isn't working, please let me
know. Since this impacted a smaller set of users, I decided to move
forward keeping us on the new connection while we work out these IPv6
issues and not roll back.

Thanks again for all your support and patience!

They have built a completely new network and this migration will finally move us over to that new network. This will eventually give us access to even more bandwidth and will also move us off of their "legacy" network. For now we're just moving from one 10G uplink to another 10G. But we're planning on upgrading this to 40G or 100G eventually.

We will be shutting down the current uplink on one router, and bringing up the new uplink on a different router. I will be on-site in case there are any major issues where I need to get direct access to the switches.
