According to a staff bulletin put out Saturday morning, a "corrupted
electronic file" uploaded overnight meant that any oyster used before
09:30 was hotlisted and permanently disabled. The figure on the
bulletin that I saw said that it could be as many as 100,000 cards that
had been killed. The, admittedly few, stations I went through yesterday
all had their gates set open, so no-one would need to touch in or out
to access the system or leave

Interesting. The media is mainly covering the aspect (which sounds from
your information like a hoax) that people only-touching-out, later in
the day, will pay penalty fares. If no-one is touching out at all (and
indeed 100k people couldn't touch out anyway) this sounds improbable.

TFL is compounding the situation by saying that these penalty fares will
be cancelled automatically in a special operation.
