This isn't uncommon, however, as Nexus phones have always sold out quickly in years past. The Nexus 4 was out-of-stock constantly when it was released in 2012.
It's unclear whether or not the phones are just selling extremely fast, or if Google isn't making enough of them at launch.
Either way, it looks like Android fans are eager to get their hands on the new phone:

The Nexus 6 literally sold out in 1 second and I've been refreshing the screen every 15 seconds w/ auto refresh since I woke up this AM.

The Nexus 6 is Google's largest and most powerful Nexus phone yet. It'll be available at full price (starts at $649) in the Google Play Store next month, but this is the first time all five major US carriers will be offering the phone as well.
