It's clear that NameJet got a big batch of premium-ish reserved names from Afilias to launch their .IO backorder auctions, and that Afilias has been reserving more and more dropping names in the last few months and they are all going to NameJet. It's not clear if NameJet now has exclusive first dibs on expiring .IOs or if other registrars like Park.io / Dynadot / Hexonet will still have an opportunity at those names.
