From PrimeGrid News Archive:

17 May 09:

We are going to have a one to two hour downtime tomorrow, May 18, at about 12:00 GMT, because the servers have to be moved to a different rack as the datacenter is upgrading their infrastructure.

Note form Cruncher Pete: 12:00GMT on May 18 equates to 10:00 E.S.T on 19 May 09.  This will also effect BOINCStats as they are co-located in the same building.

We have released a version of AP26 application for 64bit Solaris (on AMD x86_64 or Intel EM64T CPUs, platform name x86_64-pc-solaris).
