During the past couple of months, I’ve noticed that Qualitynet users (at least the ones I know) have been having strange connection issues. Randomly, for about an hour or so, P2P networks would be working, but websites would stop loading on their browser.
After looking into it, I figured it was a DNS problem, which makes sense since P2P networks communication is via IP addresses so there is no DNS intervention. Also, local websites (such as this one) or ones hosted in the middle east would work fine.
One way around this is to use OpenDNS (although I couldn’t test it at the time), another is to simply call and complain about their DNS Servers (don’t accept the a-shark-bit-our-cables excuse). If you’re a geek though, you’ve probably memorized all the IP addresses to your favorite websites anyway :P
