Lack of knowledge? My friend left for work at 0615 this morning, and said the gates were closed at Wood Green, so she touched in as normal (but a '1' flashed up on the display rather than her balance).

You mean there was a very similar incident 16 years ago?

The Nottingham City Transport smartcard issue in around 2006.

But what is special about 1/1/2016 compared to 1/1/2015, 1/1/2014, etc?

Or 1/1/2006 compared to 1/1/2000. There's something about the range of
years for which 1/1/xxxx is recognised, which transcends xxxx=2000.

I think that's called "not understanding the exact nature of the outage
and not wanting to be caught deliberately evading fares, even if for a
short time TfL will decide not to worry about it".

It wouldn't surprise me if they are looking at introducing this in
Netherlands as the whole country is zoned.

The Dutch railway system over the whole country is about the same size
in terms of number of stations and permutations of routes as TfL is in
just London. Try Zoning the non-TfL bits of the UK and there will be so
many winners and losers you'd never hear the end of it.

There is also the crazy notion of "honesty" and "believing in paying for a
service because it's the right thing to do", which is not in fact entirely
lost to the world...

(Back in the day when I travelled regularly between unstaffed stations with
PERTIS machines, I actually used to pay my fare in full, or seek out the
guard if I didn't have enough change. Strange but true.)

That's not the millennium bug then. It was about years being held in 2
digits so not able to handle properly to rollover of the century.

It's the same class of problem, which is why I put the "Y2K" in quotes.

Well they quite evidently didn't test for some condition otherwise the failure
wouldn't have occured.

This is simple. Oyster cards hold value on the card and are read,
processed and then written back to with an updated balance and journey
history. In order to work out a PAYG fare or extension fare then you

I'd love to know how many hacked Oysters or DIY cards are out there that
can be loaded with a random value and/or don't decrement the value.

Presumably the "read" part of the above has some form of linked
reconciliation which quickly identifies and blocks those cards?

Not when the original MiFare was hacked they didn't. Anyway, if its DIY
card they could easily program in a rolling Id number. I doubt if the gates
keep a list of every single valid card thats been issued, probably just
blocked ones if anything. Presumably the version 1 cards are still valid so
that hack could still be used. Which probably means it is.
