Going to its website (http://oracle3.foldingathome.org/) from the server status page gets a timeout. Pings fail as well, but I do not know if a firewall is discarding pings or if this is due to some other reason.

Actually it is up and has been for a day. The server is slow on responding to connections, they are looking into that. Some WUs are being successfully uploaded, it may just take time and a few retries to get a connection going.

When a server has been down some WUs may have been accepted by a Collection Server in lieu of the Work Server. Other WUs may be refused and retained by FAHClient on everybody's local storage. When the server comes back online, there can be a backlog of those WUs waiting on everybody's machine and this can saturates the WS's bandwidth. Connections have to be limited so that the server's bandwidth is utilized effectively without being exceeded until the backlog can be processed.
That might explain the slow response ... or it might be something else.
