"Test Connection" feature of MapTool Offline
As of today it appears that the Test Connection service is offline again.
Testing shows that the server is offline as of April 21st and probably quite a bit earlier. When the server comes back up, I'll expire this notification and it'll disappear from the news panel on the left side of the page.
The configuration of the server with respect to the test function is convoluted, but I don't expect it to be down for long. :)
And yes, we have plans to make this system a bit more robust but it involves a little bit of work that isn't finished yet. :(
An alternative method of testing your connection is outlined in this thread on our forums.
