Interestingly enough, we have a lot of websites in the area - a couple
of major data centers in the Reston, Va. area, for instance. And none
of them went down. Sure, they lost power. And at least one lost part
of their communications link. But none of their sites were down.

Bullshit. Single lines go down all the time. Work needs to be done on
the cable, for instance. Or an amplifier goes out. Or a car hits a pole..

It's not MY fault the sites you visit are in a third world country with
dodgy infrastructure. My customers' sites are hosted by reliable
companies in datacenters with reliable backup.

Sorry to hear no one noticed. I just took down a server Friday to
update some software. It took less than 5 minutes, but before I
finished, they were on the phone asking why the system was down.

I have never lived anywhere that you don't get occasional outages.
Nothing is 100% reliable. Too bad you don't notice.
