We appear to have hit some kind of bug on the LinkOregon side where any of our IPv6 subnets above a certain range just don't work outside of the router. They have a case open with the vendor and they are looking into it. I've reached out to the affected parties and they're all OK with waiting until it gets resolved (even if it's a few days away).</span></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><span style="font-family:Arial,Helvetica,sans-serif"><br></span></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><span style="font-family:Arial,Helvetica,sans-serif">Something else I noticed until this morning was that our email relays had grabbed a SLAAC IPv6 address and were using it instead of the statically assigned one.

I resolved this at around 9:30AM PDT so any mail onward should have gone through.</span></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><span style="font-family:Arial,Helvetica,sans-serif"><br></span></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><span style="font-family:Arial,Helvetica,sans-serif">I should also note that we have enabled IPv6 on _one_ OpenStack subnet (public6 on OpenPOWER) that is _also_ affected by this outage.

I have an update on some issues we did discover after the fact. For<br>
now, everything with IPv4 seems to be 100% OK. Please let me know if<br>
that isn't the case.<br>
<br>
We did however have SLAAC enabled for a while on the other subnets<br>
where we normally didn't have it enabled. So if you see an IPv6<br>
address that is automatically assigned but it's not routable, that<br>
would be the case.<br>
<br>
HOWEVER, we are having some very strange issues with IPv6 on _some_ of<br>
the subnets. We weren't able to track down the root cause today and<br>
will try tomorrow.<br>
<br>
As of right now, it seems that this is only happening on the following<br>
IPv6 subnets:<br>
<br>
2605:bc80:3010:200::/64 (Gentoo)<br>
2605:bc80:3010:400::/64 (Drupal)<br>
2605:bc80:3010:401::/64 (Drupal Virt)<br>
2605:bc80:3010:600::/64 (Fedora)<br>
2605:bc80:3010:700::/64 (OSM)<br>
2605:bc80:3010:a00::/64 (Buildbot/RTEMS)<br>
2605:bc80:3010:b00::/64 (Debian)<br>
<br>
If I am missing any IPv6 subnet that isn't working, please let me<br>
know. Since this impacted a smaller set of users, I decided to move<br>
forward keeping us on the new connection while we work out these IPv6<br>
issues and not roll back.<br>
<br>
Thanks again for all your support and patience!<br>
