• 06:13 - First page
• 06:20 - Identified as URL probing from one IP (https://log.gprd.gitlab.net/goto/45de4837b44502762b289994c100e5bc); no real people-affecting errors. A bit annoying that broken requests show up in the same category as legit errors, but it's probably hard to distinguish automatically.
