Got a warning for my blog going over 100GB in bandwidth this month... which sounded incredibly unusual. My blog is text and a couple images and I haven't posted anything to it in ages... like how would that even be possible?
Turns out it's possible when you have crawlers going apeshit on your server. Am I even reading this right? 12,181 with 181 zeros at the end for 'Unknown robot'? This is actually bonkers.
Edit: As Thunraz points out below, there's a footnote that reads "Numbers after + are successful hits on 'robots.txt' files" and not scientific notation.
Edit 2: After doing more digging, the culprit is a post where I shared a few wallpapers for download. The bots have been downloading these wallpapers over and over, using 100GB of bandwidth usage in the first 12 days of November. That's when my account was suspended for exceeding bandwidth (it's an artificial limit I put on there awhile back and forgot about...) that's also why the 'last visit' for all the bots is November 12th.
The traffic is really suspicious. Have you by any chance a health or heartbeat endpoint which provides continuous output? That would explain why so little hits cause so much traffic.
It's super weird for sure. I'm not sure how the bots have managed to use so much more bandwidth with only 30k more hits than regular traffic, I guess they probably don't rely on any caching and fetch each page from scratch?
Still going through my stats, but it doesn't look like I've gotten much traffic via any API endpoint (running WordPress). I had a few wallpapers available for download and it looks like for whatever reason the bots have latched onto those.
