Bad CTF Bingo,instance edition.

Every instance disaster you have lived through in a CTF, on one card. Click the ones you've seen. The number of lines says a lot about how much the infra person slept.

Click the ones you've seen, then hit the button.

Got a bingo?Hand the instances to us.

Every instance gets its own microVM, images are prebuilt on every server, surges go into a queue, and expired instances clean themselves up. chall.run crosses off almost every tile on this card. Flag formats and Discord drama are still on you.
