Thanks to a note from Prissi about DNS issues, an investigation led me to find that nullusanxietas.com expired yesterday and didn't autorenew. It has been renewed now.
In the meantime, some DNS servers without IPs cached may fail to look up sites I host. This should be resolved with time as the domain is renewed (many domains use nameservers baset on nullusanxietas.com).
Pleae forgive any outages. The servers are still up, it's just the information on the internet about how to get you there, but I've done the bit I can do to get it running, it should be a matter of time.
Thanks for the fast response.
Thank you so much for the heads up!
