Hi! We looked at the logs. 21,740,641 requests are coming from a single IP without a user agent that we can't geolocate because it's in the 10 range.
Looking into the actual queries revealed that it's probably a broken bot. Stas said "the query makes no sense and is broken" and that it "looks like somebody trying to download whole DB in very weird way but is doing it all wrong."
We are investigating the issue.
