Until this is resolved, you will experience difficulty in accessing non-EECS systems by hostname from the EECS network and may also experience problems access off-campus systems by hostname from elsewhere on Campus.

The problems with DNS resolution of non-EECS/off-campus hostnames/IP addresses appear to have been resolved.
However, we are still waiting for a status update from Campus before finally marking this problem ‘resolved’.

Tonight’s problems with DNS resolution of non-EECS and off-campus hostnames were traced to problems with DNSSEC, specifically with DNSSEC Lookaside Validation (DLV) which has now been disabled, allowing DNS service to return to a functional state, and will remain disabled until the problem with DLV can be properly addressed.
This problem affected both of the EECS production caching nameservers, rhea and cronus which provide DNS service for systems on EECS supported network, as well as [those run by Campus, ns1/ns2](http://ucbsystems.org/2009/04/04/problem-with-dnssec-processing/), which provide similar DNS service for other Campus networks.
If you are still experiencing problems with DNS, please contact the [EECS Helpdesk](https://iris.eecs.berkeley.edu/05-helpdesk/) by email at [help@eecs](mailto:help@eecs), by phone at x2-7777, or in person at 395 Cory Hall.
