2014-11-26 ~1432Z: Problem with kwak.bitfolk.com, and IPv6 (all hosts)

Hi, Around 1432Z IPv6 connectivity to all hosts was lost, and VPSes on kwak.bitfolk.com became unreachable (both IPv4 and v6). Subsequent investigation has revealed that kwak.bitfolk.com was unexpectedly power cycled and returned in a configuration that had no networking. IPv6 connectivity was restored at around 1503Z and VPSes hosted on kwak.bitfolk.com are now in the process of being booted again. If you are unable to reach your VPS, and it is hosted on kwak.bitfolk.com¹, please log in to your Xen Shell and look at its console to see what is happening: https://tools.bitfolk.com/wiki/Xen_Shell There is a high possibility that the VPS is still booting, is performing a filesystem check, or has failed to boot because of some configuration problem local to your VPS. If you have ruled all of those out then please do send a support ticket to support(a)bitfolk.com. For those of you with Nagios monitoring set up I will be watching to make sure any alerts recover where that is within my power. To follow: - How kwak came to be power cycled - Why it didn't boot with networking enabled - Why IPv6 broke for everyone even though it should have failed over to another router.
