Deleting customers can take a long time

Internal metrics show this is a slow operation.

So this is not an isolated issue then? I recall card deleting taking some time as well.

We haven't been able to reproduce it. DB traces do not show any missing indices but it's certainly slow occasionally. I suspect we need to turn this into an offline operation.

Deleting a card is just flipping a bit so that should always be quick. If you have request IDs for any of these specifically that helps us investigate.
