> Banks are pretty good at not losing data

Except for that day I logged into Barclays Bank (in the UK) and half the transactions were missing from the last several months of statements.

We're talking maybe 50 transactions just gone from the bank account ledger, which had long since been settled and previously downloaded (that's how I noticed).

To be fair to them, the transactions reappeared a few days later. But it took days, and had me quite worried.
