My host and I are planning a server maintenance operation for today, Saturday March 31st, sometime between 9am and 12 CEST.
This downtime shouldn't affect too many people, given this time span is the one when AAO gets fewer visits, but still - if you happen to login at that time and notice AAO is down, don't panic !
(in big friendly letters
Sorry for not warning about this earlier !
Also, a second maintenance operation will happen in the next few days, though the date isn't known as of now.
