All maps and scans have resumed. Sorry for the delay. Availability to troubleshoot issues earlier was sparse due to the holiday. Things should be operational at the moment.
Over the past 2 weeks, Niantic has laid down the ban hammer on a number of automated accounts. The vast majority of all botters and scanners were affected directly, including us. We have lost nearly 50% of all accounts we use for scans. With that said, there are a few areas/locations that appear emptier, or even completely empty. We are in the process of creating additional accounts to replenish these areas.
