Ah right that makes sense.

It seems odd that it took them so long to identify and rectify the issue. Have they made you any assurances about what they'll do to reduce this time/prevent this from happening in future?

Specifically this class of incident? Yes. They seem to be reasonably good at operational runbooks for known flaws, so I can imagine this class of incident being handed faster in future.

What worries me is the next unknown unknown, which is why we are insourcing. One thing I think Monzo can be particularly proud of is our incident response, and debugging of our own systems at speed.

That's why this article focuses more on what actions we are taking, and not what actions they are taking.
