We are currently seeing an issue where eecs.berkeley.edu, cs.berkeley.edu, banatao.berkeley.edu, and possibly other related DNS names are not resolvable from campus networks or from the Internet. As a result, many websites appear down and emails may bounce.
We have contacted IST, who operate the DNS servers that answer these requests from non-EECS networks, and they are investigating.
Name resolution from EECS networks using EECS DNS resolvers is working properly.

Campus DNS Administrators applied a hotfix to campus DNS servers this evening, and it appears that DNS resolution of eecs.berkeley.edu, cs.berkeley.edu, and banatao.berkeley.edu hosts is once again working from non-EECS networks.
