Airtel DNS much much slower than the Level 3 servers (taking a few damn seconds to. I'm losing faith in this provider rapidly, but there doesn't seem to be much option. All other providers are much worse. Oddly, OpenDNS seems to be really slow too, but Level 3's are wicked fast in comparison (but still slower than what I was getting from Airtel once).
In addition, there are frequent outages on the DSL.
This is horrible service, like we live in the Congo or something. Will wait till next billing cycle (and lifting of throttle) before I think about shifting.
