Strange Server Problems

[Kevin]

Hi Boris,

Thanks for your reply! With Joe's help, I narrowed down the problem to IP
configurations, it turned out to be my ISP's fault, they changed something
on their side and caused some IPs to stop working, the requests didnt' reach
the server. I convinced the support to report the problem, their networking
stuff fixed the problem.
