I don’t know if anything I’m saying is related to your problem, but something has been occurring this week. There was 2 days around the middle of the week that many VPNs couldn’t connect to the internet & the local cable company’s internet just stopped working. According to employees, they didn’t have anyone working on fixing the problem either…like they knew what was happening. I live in the southeast of the US. When checking to see if my VPN was down, the outage map showed it to be out in most of the US & most of Europe. Then just as suddenly as it stopped, it started working perfectly, if not better, once again. What made it even more suspicious to me was that there was NO news about the outage anywhere that I could find…not even the BBC nor the CBC. It might have nothing to do with your problem, but maybe one or more of your sites got caught up in whatever was happening. I have my own conspiracy theory on this, but with NO proof, I’ll just keep it to myself!!!
