Multiple ECE websites hosted on the F5 load balancer (including www.ece.ubc.ca and courses.ece.ubc.ca) went offline at 16:19. Service was restored at 18:15. The outage was caused by a staff member who had dislodged a power cable to a network switch in ICCS X220.

Immediately after resolving the issue, we decided to simplify the network by eliminating the switch altogether.

Specifically, the following .ece.ubc.ca websites were affected:

  • Departmental sites: www, intranet, help, courses, id, download, groupware
  • Research group sites: adaptive, bisicl, ctg, feel, mm, intranet.rcl, rsl, www.poewiki, intranet.salt, netsyslab, winmos
  • ICICS sites: mrbs.icics.ubc.ca, inventory.icics.ubc.ca

During the course of troubleshooting, some CS servers on the load balancer would also have experienced momentary disruptions, totalling perhaps 3 minutes.
