In the wake of Saturday's mass shooting in El Paso, in which 20 people lost their lives, it was discovered that the shooter had posted a racist manifesto on the imageboard site 8chan. That was the third time this year alone that a mass shooting has involved the notorious site, and its hosting service decided that was finally enough. As of midnight on the US West Coast, the Cloudflare service provider will cut off 8chan.

This isn't the first time that the popular service provider has severed its ties to one of its customers over offensive content. In 2017, the host dropped the white supremacist website the Daily Stormer, a move that left it without a host briefly.
