[ExI] META: list server maintenance soon

[john at ziaspace.com]

Hi, all,

I'm glad to see a healthy amount of discussions on the list :)

Getting computer parts these days is hard, but the main server is back in 
operation with new parts and we're ready to switch from the backup server 
to the main server. No email will be lost because we have a backup to the 
backup, but the list web site will be unavailable for an hour or so.

This'll happen around 8pm PDT / 11pm EDT / 3am UTC.

Thanks!
John Klos
