A network problem with one of our LDAP load balancers caused some intermittent problems with some Departmental services. This probably started overnight when a server was patched and restarted. This morning we had reports of intermittent problems with Repo, and the IRIS roster and network applications on iris.eecs. The problem has been identified and resolved for now. Around 12:10pm we had to restart the server that hosts the iris.eecs website and the Department jabber server, but all services are operational again at this time.
