The parked page happens to not be a redirect. It's probably DNS TTLs. If you get redirected to twitter, you're seeing A records like 104.18.16.213 (Cloudflare). I'm seeing an A record of 34.102.136.180, which gives the parked page. I think they changed the NS records to Cloudflare and the TTL hasn't run out on the original for many downstream DNS servers.... $ host -t ns x.com x.com name server ns71.domaincontrol.com. x.com name server ns72.domaincontrol.com. "domaincontrol.com" is the parked page service.
