It's like mystery day today. Can someone explain to me the reasoning behind:
"The phone lines were flooded and it crashed the phone network."
So, the devices specifically designed to answer calls somehow "crashed" when... answering calls.
I can imagine phone lines becoming "busy", I can get them going down because of a power failure (as nobody uses the line power to power the phones any more, but even then - UPS?). But I don't get the excuse that something "crashed" because you asked it to do its job.
It's not like it was madly trying to perform the impossible and overflowed it's "calls in progress" integer stored in a byte or something. It has X lines, they are either on a call or not, why can't it handle it?
Which makes me suspect, as I already have for years, that "something crashed" is the excuse trotted out by IT departments when something is underspecced, or just not working as it should.
Crash has a particular meaning, you know. If your phone system crashes because of the number of incoming calls, then it was NEVER designed to handle that many calls. And that means you bought the wrong thing.
