I have recently changed domains of my website via 301 redirect, and I have had a member complain that ever since switch he gets a timeout when trying to go to my site, however he can view my site if he accesses it via proxy. His entire home network is doing it, he tried flusing dns, reset modem, clear data bla bla, basically everything almost on web. He has comcast internet, and he tells me he can view site via neighbor internet. His IP is not banned from my site. What is wrong? Is it my site issue or his issue?
