Why have I not received the Nougat OTA yet?

AC Question

I have a Nexus 6P, so ideally, the ota should arrive first, or in the first week of release (22nd August). It's now 7th of September, and I still have no OTA, but my friend who lives 3 minutes away got the update at the end of August.

Question is, is this normal for the flagship Nexus device. Do I wait it out? If I flash it myself, will anything wipe?
