Twitch was hacked massively last week. It’s estimated that a total of 125GB of data was released by the hackers, including source code to the website and included the top streamers revenue, as well as a slew of files with strange pizza references. Why you might be wondering? In 2014 Twitch was hacked in similar circumstances, and the response was code-named “Urgent Pizza.”

According to a new article from Vice’s Motherboard, which delves into the intricacies of the Amazon-owned streaming service’s first security breach, this would appear to be the case.

Former employees told the publication that they had to spend months basically rebuilding Twitch from the ground up at the time. For two months, one person claimed to have worked 20 hours a day. For “three weeks straight,” another didn’t stop working. To cut down on commute times, several people even rented motels near Twitch’s workplace.

Twitch also demanded, according to one source, that all future hack instances be given a food-themed pseudonym. Files from this week’s hack include code for a random food-name generator, which may be used to that goal.

Not only are there multiple cryptic references to pizza in the files, but it’s not only because the engineers were hungry. “Remove pizza script,” “a pizza thing,” “signal that the server is ‘urgent-pizza clean,’” “transfer pizza to securelogin,” and “dirty status = True,” according to Motherboard.

That final part is an allusion to the 2014 Twitch servers that were hacked. According to Motherboard, the streaming platform left several servers operational but shut down as part of operation “Urgent Pizza,” marking them “dirty” as a warning to anyone working on them.
