We have two networking downtimes scheduled for September before classes begin.
Sep 12 (Wednesday) – the night of the powerdown
Although the data center is usually unaffected by the power testing, we going to be decommisioning a piece of old network equipment. Expect a few data center systems to be unavailable during the work (which should happen between 8pm and midnight). This outage will be in addition to various Linux login servers that are being upgraded to a new version of Linux on the same night.
Sep 20 (Thursday) – 8pm to midnight
Most MCECS network gear will be rebooted to install software patches. Expect rolling network outages across FAB/EB (and potentially MCECS networks in Ondine and the SRTC basement) as the equipment reboots. (The work should be done by 9pm but there is always the potential for problems.)
