Frankly, I'm surprised things like this don't happen more often. Kudos for the incident management. Also a big plus for having working backups, it seems.

I wish that account was still updating.

This reminds me of my undergrad CPSC days. The CPSC department had their own *nix-based mainframe system that was separate from the rest of the University. The sysadmin was a pretty smart guy who was making less than a third of what he could get in industry. Eventually he got fed up and left. About a week or two later the servers had a whole cascade of failures that resulted in everyone losing every last bit of work…

The BOFH sabotaged his systems before departing? Didn't build a backup plan? And they hired him back?

You know what? Fuck them. Fuck higher education completely. Undervalued and underpaid is the name of the game for any important IT roles in that shit hole of an industry.

There was a similar catastrophe at Jewel osco stores many years ago. Nightly, items added to the store pos were merged back with the main item file at each store location. The format of the merged data was exactly the same as loading a new file, except the first statement would be /EDIT instead of /LOAD.

One of the programmers decided to eliminate some code by combining the two functions, with a switch to control whether /LOAD or /EDIT was used for the first statement.

There was a bug in the program, and the edits were sent down as loads.

A guy I knew, Barry, was the main operator that night. He started getting calls from the stores after around 10 of them had been reloaded with 5 or 6 items.

Barry said it was the first time he got to meet the president of the company that day.

This was back when phone lines were used to transmit data, and it took several hours just to transmit an item file. So, the store locations were out of business until the item file could be restored.

Isn't this more the fault of the system architect than the guy who accidentally fired the bad deploys? It's similar to a database firehose: If you accidentally start deleting all data you should have a quick working backup ready to quickly bring the dead box up to production.

I don't know. This could very well be a case of not much more than a bad drag and drop in SCCM. Its not quite that simple, but I'm not sure this is some custom process they setup.

Not quite as disastrous but when I was at university the resident administrators configured the entire site's tftp server (everything was netbooted Suns) to boot from the network. This was fine until there was a site-wide power blip and it was shut down. When it came back it couldn't tftp to itself to boot because it wasn't booted yet (feel the paradox!). Cue 300 angry workstation users descend on the computer centre with pitchforks and torches because their workstations couldn't boot either...

Bad stuff doesn't just happen to Windows networks.

I _very_ nearly did this whilst working for a University back in the early noughties. Luckily I managed to get to the server before the "advert" activated and wiped out everything. It was so easy to do I am surprised that it is stil possible. I feel for their pain, but it does sound like they are doing a good job of mopping up. I did allow myself a snort of laughter when I read the bit about the server being re imaged as well. That is pretty darn impressive carpet bombing the entire campus.

Forgive my beginner question: Since a reformat was done to the affected machines, does this mean that researchers' datasets, drafts of papers, and other IP were lost? Or were researchers' machines not affected?

Deletion and formatting doesn't necessarily destroy data, it just destroys the pointers to the data. If they're lucky the data can be recovered via software utilities (undelete) with backfill from backups. If they're unlucky then important and un-backedup data has been written over, and those people are going to be SoL.
