Maintenance tonight [Nov. 20th, 2008|05:58 pm]
Doug Ayen
I hate these, but they are part of the job. 3am - 7am maintenance window, migrating customers off of one set of archaic routers onto some new ones that still have the shiny on them (juniper MX 960s). This is the third this month, and these maintenance are getting really old fast.

Everything is prepped on the routers (it took about ~15 hours to migrate the configurations), the field engineer should have done his bits, so in theory, it'll just be me telling him which patches to move when, then activating the new configs, deactivating the old configs, and confirming it all still works. Given what we've seen in the past, I expect between 10 and 25% failure rate on the customers coming back up.

After that, a cow-orker piggybacked a switch supervisor card replacement at the same location onto my maintenance. We'll do it only if the main maintenance goes quickly and smoothly, but it means that this most likely will be a full-maintenance-window job.

In short, despite my plan to try to go to bed as soon as I get home, I expect to be quite short on sleep tomorrow, and this will disrupt my sleep schedule for several days. Hello insomnia and falling asleep at the wheel! As I also have an ongoing cold, I expect it'll now last even longer.

In a word, suck.
