This wasn't Pluto's fault, it was mine. I messed up a DNS entry, and then once I noticed and fixed the problem it took hours for the fix to propagate to every DNS on the internet. I've been working on getting e-mail working on linuxmce.org, so that messages can be sent on svn checkins on the new svn located there. And for the e-mail to work reliably reverse DNS needs to be working, which it appears to be as of this morning.
Whenever there are unexpected outages you can be sure to find me on the IRC channel #linuxmce shortly thereafter.
FYI There is a new "CHAT" button in the forum software now, that will bring you to that chat room, assuming of course that the problem isn't with the website. In that case you will need to use a third party chat client.
