Yeah, so my registrar canceled my auto-renew and, as a result, my mirror (arch.mirror.square-r00t.net) is inaccessible via DNS. It's been rectified, but it of course hasn't propagated everywhere and their TTL for the SOA they replaced mine with (UGH.) is frustratingly high.
Long story short:
- services should return to normal within 48 hours - there is no such thing as a good registrar
Thanks, and sorry again.
