Hmm... Interesting. I'll have to possibly call my ISP then. I've tried everything you mentioned, and still having the issues.
I'm also having the same problem with the project 1999 website. In a command prompt I can ping any website I can think of and have 0% packet loss w roughly 15-20ms ping, but I get 60% packet loss when I ping the
www.project1999.com website. I'm not tech savvy enough to know if I can ping p99's servers this way, but it seems like I'm specifically just having a problem with reaching the p99 servers.
