Thats very interesting. I wonder if its anything like when this forum times out for ether a user or two/ sometimes the whole site is down for so many minutes/days. I think that whatever it is, its the host AG's problem and not yours but the information provided. I think it may of been Potatoes and Pie on here recalled this happening but then AG fixed the problem later. So with that understanding and problems of late with AG and that game apparently, just waiting will solve it.
I think that's just armor games website either crashing or failing to simply load but either way it has nothing to do with Shellshocklive it's self.
