I have experienced off-and-on access to The Wargamer for the past month and more. wargamer.com is unreachable for a few days, then reachable, then not again, then ...
It's the same story here from multiple systems running difference OSes (variants of Windows, Linux, Mac OS X).
Comcast is my ISP.
I suspect it's a routing misconfiguration somewhere, or maybe an obscure DNS problem. (IPV6 related? And if so, might we expect to see many more of these IPV4-to-IPV6 conversion glitches?)
This affects Wargamer only. During these outages, Matrix is unaffected. (I can always reach Matrix. Also, from work I can always reach Wargamer. It's only from home, with a Comcast connection, that Wargamer is sometimes inaccessible.)
More data points.
For me both are 100% unavailable from home (Comcast) but 100% available at work (AT&T) and with the same PC on both. And only since last week. Before that I never had any problems.
