Not only East Coast, Twitter can't be resolved in Ireland/UK right now (I assume the mobile app uses some kind of 'dns pinning' as that is working)

The app was down for me until I switched my WiFi network to use OpenDNS. It's possible your phone has the DNS record cached, or it's using a different DNS server. (Is it on cellular?)

Hardcoding IPs into a mobile app typically isn't done because it makes changing your infrastructure extremely painful.
