I'm from Brazil, and currently, our ISPs are dropping any requests for the Twitter IP range (AS13414 Twitter Inc.) and refusing DNS queries on their servers.<p>If a user is already using Cloudflare DNS (1.1.1.1), wouldn't moving Twitter to Cloudflare make the block unfeasible? What are the downsides from a business perspective to not migrating? How much would it cost to migrate Twitter to Cloudflare?<p>Edit: Yeah, they could just ask Cloudflare to block it, but what if Cloudflare refuses to do so?
