Comcast DNS outage



Comcast is one of the US largest broadband Internet access providers with 7 million subscribers. On 7, 12 and 13 of April, there were three cases of DNS breakdown, each case hit at about 8 p.m. and lasted three to four hours. Users could not surf web sites or get email during those times.

Because of the unstable nature of Comcast’s DNS, some users have decided to manually configure their client PCs to use Verizon’s DNS servers. Sounds like these users are pretty clever.
