Problems with Lloyds Bank & TSB cashpounts attributed to failiure of 2 out of 7 servers by BBC.
Interesting article on BBC Radio 4 Today Prog this morning. Apparently last night some Lloyds & TSB customers were unable to use their debit cards for a couple of hours or so. Not me. I was at home.
The point is that apparently two servers were down. It’s a bit of an eyebrow raiser that this could happen with just two servers going down. Doesn’t sound like good capacity planning. I’d have thought they’d be load balanced with plenty of headroom on each server that would allow for such an eventuality.
Can’t be right unless there’s something specific re security for such systems that doesn’t allow them to do that.
One wonders what would have caused two servers to go down at the same time. Rack outage maybe? No generator bup? Suspect we won’t find out and I’m only mildly interested.
The other observation relates to that comment by the reporter re people at petrol stations whose cards were rejected. Unless they had alternative means of payment they had to wait at the petrol station until someone came along and paid for them.
Petrol stations in my experience can fail over to a manual card swipe using old fashioned slips of paper. Maybe not all of them. Or maybe because the card processing system was not “down” generally the specific Lloyds customers weren’t trusted.
PS no such thing as 100% uptime – see this post on Vodafone outage
