[2010-01-31 20:52:44 | Mike Howard]
IST staff confirmed that hmmb4fes, a switch in Hearst Mining, failed at 8:03pm Saturday.
IST was planning to reload that switch on Monday night due to memory leaks, but unfortunately it failed before the scheduled maintenance window. Network engineers had to go to campus to reboot the switch; connectivity was restored at 8:14pm Sunday.
The wireless access point in 360 HMMB is still offline. IRIS staff will investigate on Monday morning.
