As a matter of interest, is there anyone whose on-line Oyster journey
history contains no omissions at all?

Mine was pretty good (not noticing omissions) up to March. Delayed
maybe: from yesterday to perhaps 2 weeks delay in showing up. It turns
out that my card's balance is correct, but Bank has indeed gone
missing from the JH.

TFL are missing another trick he there's no point worrying all of
us when a simple professional status web page would suffice. It would
cause fewer calls to their call centre.

I had the opportunity to check my journey history on a ticket machine
yesterday, and as expected, all was correct. More surprisingly, the
on-line history is now also correct. I don't know if that's as a result
of my ticket machine check which perhaps caused some corrupted data
buffer to be re-set, or just that they've fixed the system for everyone.


The latter. The issue here is not some fundamental problem with the
underlying central Oyster database, but the presentation of journey
history data in the Oyster online account system (i.e. what you see
via your web account). I've no idea on the specifics of how the online
journey history system sources its data from the central Oyster
database (could it happen on the fly? I'm not so sure that's how it
would work), but the problem is some sort of disconnect between the
definitive central Oyster database and the system that prepares the
online journey history - this may have only affected some as opposed
to all the online accounts.

If there was some sort of problem with the central Oyster database
then all head would have broken loose a long time back! The central
Oyster database system basically needs to have quasi-bank like
reliability - it's unlikely something would go wrong with it. This
online journey history problem is all about the mangled presentation
of that data - or more to the point only some of it - as opposed to
the underlying data being mangled.
