Hi all. I have moved the cluster to its new host and some of you appear to be struggling to get in. The correct address should be gb7mbc.net port 8000. If any of you are using gb7mbc.spoo.org, that appears to have gone. You could also try using the IP address directly. 22.214.171.124 port 8000.
If you need to troubleshoot, try a terminal client like putty. I hope this helps. Ian
