Tu, July 18, 2017: nebula-1 and nebula-2

Two new servers have been added to the open compute pool. Nebula-1 replaces a host that died some time ago, and nebula-2 replaces a very old machine.

If you were using nebula-2 for compiling certain libraries, it has been renamed to nebula-0. It will be take out of service once the last few SL6 machines have been upgraded to SL7.
