Hi everyone, We just changed the IP address for websignon.warwick.ac.uk and webgroups.warwick.ac.uk. You shouldn’t have noticed these changes as they should be seamless. We are still listening on the old IP (137.205.243.28) and the new ones (137.205.243.171 and 137.205.243.121). However, we would like to stop using the old IP. As Java caches DNS lookups, it will require a restart of JBoss and Tomcat instances to pick up the DNS change. I’d like to ask everyone who uses Web Sign On or WebGroups to try and schedule a restart as soon as they can. We will monitor the usage of the old IP and see how the switch over goes and chase people who don’t change :) This is in preparation for moving over Web Sign On and WebGroups to a new server. By switching to the new IP address it should mean we have no down time at all when we do the switch. Thanks, Kieran
