We're still having trouble with our connection with all Neustar-operated registries (.biz, .cn, .co, .tel and .us).
Our operations team continues to be in contact by phone with the right people at Neustar as we both work though what's causing the problem with our connections. Neustar has confirmed that other registrars experienced similar issues today.
Sorry for the trouble this is causing. It's all hands on deck here to try and figure out what's at the root of the problem and to get service restored for these TLDs.
All other OpenSRS services, including lookups and management for other domain extensions are working normally.
