My apologies for the delay posting this. The site was, indeed, down for a few hours yesterday, from around 5:00 p.m. to 9:30 p.m. (GMT -7/ Arizona time)
The electricity in the region our site is hosted in had been turned off in response to a local wildfire.
As always, thank you for your patience on these kinds of things!
Looked at the pic full size and I think you're right about the KBD protector.
Nobody's mentioned running the boards through a dishwasher (no soap) for cleaning. Your computer preservation budget should probably include a sonic cleaner tank made specifically for the task, if not I'd buy a beat up used dishwasher dedicated to cleaning that kind of industrial crud!
