So who did BA outsource their IT to?

Indeed.
Every contractor should have a taxi company on speed-dial. You never know when you might need a fast car to the airport.

Even if it was meteorite hitting whole datacenter and destroying everything - they should have had another one hundreds of miles away as backup ready to go at moments notice.

Certainly BA had that 25 years ago and even 40 years ago. If the main DC blew up, the second site or DR would take over seamlessly.

The above strategy is still used by major banks and corporate's and works fine. I think what BA is saying about their outage is 100% BS. Someone has screwed the database badly and it has been made worse by a bad fix.

I have tested bank systems where you can pull out the plug on a DB server and on restart the TTM will recover without loss.

Certainly true now. However in 1991 I was working on UBS trading floor. Someone decided to test UPS at about 10am one day. It as about 3pm before trading started to resume. Thankfully things have come a long way.

Telegraph looks like its just the Home page

Telegraph that, for months, tried to block non subscribers by using cookies.

ToryGraph turned into poor cousin of The Daily Mail - click-baiting tulip behind paywall: they keep praising May as if those Brothers want some massive favour from her...

I had already given up before the paywall.

Are we really supposed to believe that a company as large as TCS do not have this level of basic protection against outages?

Either TCS are a complete and utter bunch of incompetent bollock juggling idiots .....

Gets my vote

I'm 5 years out of date with bank DRs but you used to be lucky if the switch happened within 4 hrs after the decision was made, which itself took 3-4hrs. Given the chances of it actually being needed and the cost of regular testing I doubt it has improved significantly. I did work for one of the largest banks and we were pushing the limits of technology even when everything worked, worst case DR would be seriously stressing the technology.

DR testing often has a period of checking everything is in-place and worked correctly before commencement, such as checking all the backups actually worked before DR is invoked.

I do recall one incident when standalone testing the UPS generators blew everything because they weren't isolated
