Call of Duty: Black Ops 6 accounted for 19% of Comcast Internet traffic last week

You might think that since Call of Duty: Black Ops 6 (which was released last Friday) is the 21st game in the franchise, it wouldn’t be that highly anticipated. You’d be wrong. Last week’s entry set multiple records when it launched.

Specifically, Microsoft CEO Satya Nadella said the game set new records for Game Pass subscribers, particularly for a first-day game launch. That’s, of course, to be expected—Call of Duty was a major reason why Microsoft acquired Activision, the longtime publisher of the series.

It gets a little zanier, though. The Internet service provider Comcast says Black Ops 6 was directly responsible for 19 percent of its overall traffic the week of the launch, according to a report in The Verge.

That’s partly due to the game’s popularity, but it can also be attributed to its huge file size. A full install of Black Ops 6 can take up to just over 100GB, depending on your platform—and possibly as much as 300GB if you also install game modes tied to the previous entries in the series, like the immensely popular battle royale Warzone. That will wreak havoc on users’ data caps; Comcast imposes a 1.2TB monthly cap in many states.
