I see more and more comments about ASSTR.org being down. That site, like this one, is funded by donations, and I'm pretty sure that the donations aren't sufficient to pay a full-time webmaster to keep an eye on it at all times. It has been down a lot in the last year. The maintainer has pointed out on several occasions that expenses are piling up and it is not possible to immediately pay for repairs, the site will be back up when repairs can be paid for.
The current issue appears to be that they have configured their web server to _only_ use HTTPS, to refuse to fall back to HTTP if there is a problem, and on the 14th their HTTPS security certificate expired. Until they get an updated certificate or they allow HTTP connections, the site is down even if the server is fine.
Folks, I don't think that the certificate is free. Without donations, that site may never come back. Similarly, SOL isn't free to run, either. Just sayin'.
