they are calling gmail an app these days? anyways. mgcarley had major issues with gmail recently. i think his account was inaccessible for around a week. last i heard he was backing it up on his computer with plans to mirror it on another gmail account for safety sake.
I guess he's opening it from Chrome(homepage -> apps)
the gmail app i believe connects to the offline edition of gmail which has a different URL and right... if gmail fails to load, it tends to show a message like account under maintenance or something like that.
