It seems to be a problem with Aliant that happens once per month or so, but not for all Aliant users at the same time.
During such times when some users can't reach the site, other people still can (on Rogers, etc.), and even many other Aliant users can reach the site.
We haven't determined yet why it happens, but it appears to be a problem at Aliant's end... it basically seems like their systems forget how to reach the site (for www and/or non-www URLs), and end up taking 12-24 hours to re-map it.
Thanks for reporting it
For anyone who works at Aliant, if you could let us know why this might happen, it would be much appreciated
