The new server is in place, and running happily. We’ve already seen download activity in excess of what the old server could do, so that’s good. We’ve also fixed one or two broken mirrors, while we were at it.
If you notice anything that isn’t working properly, please let
board@muug.ca know!

Hello, all.
We’ve been working on the new server for MUUG for quite some time, and we’re ready to (try to) switch over this Friday, Jan 7th around 19:00 (7pm). Since this is a bit of a shoestring operation, we expect this to go well, but
not necessarily perfectly.
The server currently provides these main public services, and the new server should just continue these (more or less) uninterrupted:
One area of concern is sendmail/mailman, i.e. the mailing lists. So if your emails to
roundtable@muug.ca (et al.) aren’t working, there’s probably a good reason for that!
The other area that might cause problems for some users, is the content mirroring – some upstream sources apply ACLs such that only the production MUUG server can rsync from them. We’ve done our best to mitigate that, but it’s possible
that it could take a day or so to fully catch up.
So if you notice anything wrong on Friday or Saturday… meh. Let us know, in case we aren’t already aware? But there’s a fairly good chance we already know and are already trying to fix it.
However, if you notice anything wrong next week – definitely, please tell us! That most likely means we’ve missed something. If emails to
board@muug.ca don’t seem to work, email me directly at
athompso@athompso.net.
Huge thanks go to Sean Cody and Ken Zorniak from
Tangent Animation for allowing MUUG to acquire newer, known-good hardware, at a price more appropriate to a group that only charges a $20/yr membership fee!
