I'm certainly glad I wasn't flying today! All was smooth when I flew
out
from Heathrow on Wednesday, and I hope it will be back to normal on
Friday.
But I wonder what effect it's had on trains serving Heathrow and
Gatwick?


Possibly longer dwell times at Gatwick Airport as people turn back home
when they either give up or realise that they are not going to fly out
today? This might have a knock-on effect on schedules into and out of
London.

I think that the effects would be as bad at Heathrow as Piccadilly Line
trains have extended dwell times at all the stations, IIRC. The same
goes for HEX trains, yes?

So cheap offshore IT work has gone well for BA? :-)

Are they not claiming it's a power supply issue? Is the hardware
offshore as well?

according to El Reg

"BA has a very large IT infrastructure; it has over 500 data cabinets spread
across six halls in two different sites near its Heathrow Waterside HQ"

The obvious question then is whether any other part of the Heathrow
area suffered power supply problems.

Heathrow Waterside is a separate industrial estate just off the A4 to
the north west of the airport (roughly where they want to put the third
runway! Apart from BA the only other occupants appear to be a branch of
Waitrose and a hair dressers.

Can you buy lemon-soaked napkins at Waitrose?

But no telephone sanitisers?

Eventually, if you wait long enough.

Not listed, they may have died out.

The power feed into the building is only the beginning of the sequence
of potential points-of-failure.

True. I thought of this after I posted. The 'power supply' in my
computer here is not the same as the power supply to my house.

Yes, I've got a 6hr laptop plugged into a UPS, which if the laptop power
supply was the only[1] sink would last another day. Mifi-style mobile
connectivity through a mast on a different substation, and that's most
of my continuity issues solved.

Doesn't scale to whole datacentres, though.

[1] About one minute's unplugging of other stuff.
