We are still monitoring the situation and trying to do restarts on our scans when things become unstable. The service we use to make calls to Niantic for scans is having server side problems due to scaling. Using this service helps decrease our costs with captchas so unfortunately we are bound to their availability.
With that said, scans and maps remain at an intermittent status. I would expect it to remain this way for the rest of the evening. Hopefully things will be resolved on their end tomorrow morning.
Sorry for the inconvenience again.
