On the last 4 hours i've got 200+ requests failing on azure table reporting `409`. I've looked around and this means PK duplication. Since this is a table specific for logging, I really don't care about the keys so my `RowKey` is `Guid.NewGuid()`...

Is there another reason for azure table to return a `409` or I'm actually seeing UUIDs colliding?

PS: i really hope that there's another reason, because on the last 4 hours I've handled only 50k requests...
