What happened to the site?

I think it went down for four or five hours. 

Hope they get a refund from their service provider for the outage- this isn't the first time.

Didn't notice.  Been running trains and getting outside.

Stuff happens, appears to be fixed, nothing to see here.

Probably for the best -- too many people spend too much time on line and not enough time building models....

Thanks for the concern guys.  We contacted Crowdstack and it appears from their response that there was a major power outage at the location of the main server.  It was serious enough that our site and likely others were down for an extended period of time.  We were helpless to do anything about it however it is now fixed and we are back at full steam ahead!  Sorry for any inconvenience this caused and we certainly thank you for your support!
