The performance problem with project.eecs is also impacting the department’s mailing list server, lists.eecs.berkeley.edu. At this time mailing list messages are not being processed.
The problem appears to be with the network switch that project.eecs is connected to. Staff are still working on the problem and will post updates when we have more information.

The project file server performance problems have been resolved and normal service has been restored.
The partial failure of a 10Gb network port on the file server led to performance problems and packet loss throughout the day. The system has redundant failover, but because the failure was only partial a take over by the partner device never occurred. Instead the 10Gb link was flapping up and down while the two 1Gb links on the same device continued providing some amount of service, but each time the 10Gb link tried to come up it caused packet loss. Service was restored by connecting one of the other 10Gb ports on the device. We are working with the vendor to replace the faulty ports.
