I've noticed a substantial increase in traffic from Ashburn, Virginia starting November 2020. This particular city is well known for data centers, which leads me to believe that this traffic is bot-related. I have IAB bot filtering rules enabled, though it's possible that those rules aren't being updated by the IAB like they used to.
Anyone else experiencing something similar?
I checked this and I do not see any unusual traffic, in fact I noticed that the trend is similar, it increases from Jan to July and then decreases from August to December and then goes back up again.
