No, it's not a Presence Service bug, it's a Sugar bug (the sugar.presence
module is part of Sugar, and it's that module that will have to be changed).
Please assign to component Sugar, with owner smcv or morgs, and keep the
'collaboration' keyword (we use that to keep track of collaboration-related
bugs in other people's components).

Was all this done on a machine exhibiting the failure you mention?
PS makes an unlimited number of connection attempts, with a short
delay between each one (we should probably change this to use an
exponential backoff process so the delays get longer as you're offline
for longer, up to a maximum of perhaps 10 minutes).

Like I said, the PS doesn't check whether the server is accessible, it
just optimistically tries to connect anyway. I believe this is the right
thing to do.

Not recently with XOs, I must admit (downloading filesystem images takes
a while) but it's always worked fine from my jhbuild.

Talk to me on #sugar when you have an Internet-accessible XO that's
exhibiting this problem. I'm smcv on IRC.

It's possible, but it's always worked for me...
