For the last few days, I've been noticing my DNS lookups are much slower than usual. Today I actually had to retry several times because of timeouts in a proprietary registration application I couldn't control. I decided to bypass the OpenDNS servers and go back to those provided by my ISP. Strangely enough, my browsing is back to normal speed after making the change. I tried to look at their system status link but got a blank page back after quite a long wait. I wonder if OpenDNS is a victim of their own popularity? Something is causing their web site to behave so slowly.
I guess I'll wait a few days and try them again to see if this is just a short lived glitch.
