Gab, a "free speech" alternative to Twitter that's popular with the far right, has been shut down after losing service from a number of mainstream technology platforms, including PayPal, Joyent, Medium, and GoDaddy.

"Gab is under attack," the company's home page now reads. "We have been systematically no-platformed by App Stores, multiple hosting providers, and several payment processors." Gab is working to get back online using new service providers.
