Hi Matt, all! Not sure if we've sent anyone so far, but there's a
regular face-to-face meeting each Thursday?

The Sunday outage was short and quick from our point of view, between
6am and 7am. IPv6 in particular was working fine that afternoon -
although I see Cloudflare's 1.1.1.1 is still blocked on IPv4.

However, sometime late on Monday? and continuing now, IPv6 connectivity
between our part of UWA and the world has broken.
