Further to my previous posts on SL weekly updates - the grid is open for an hour, then taken down again - Why don't you just bite the bullet, be realistic, and say the SL is only open 6 days a week? As has been mentioned elsewhere in this forum, effectively it is already for us Europeans. If you make it an official policy, rather than just announcing down time between certain hours, then at least people will know for definite not to schedule any events on a Wednesday.
And if the update schedule was monthly, rather than weekly then (a) 24 hours downtime wouldn't be a bad as weekly and (b) There's be more time to test the updates on the live servers before cheerily announcing that the grid is open!
Personally, this up-down-up saga on a Wednesday has become so regular that I don't think I'll even bother trying to log-in at all on Wednesdays any more.
Edit: And speaking of announcements - the grid is down, but the only announcement is the 1.12 Release Notes?????
Edit: Oh yes - Just saw the blog (Thanks Lizbeth!). Does having a blog instead of a forum mean that future updates will go more smoothly? ;Q
