We are currently facing connectivity issues with the .CN Registry. Due to this, you may not be able to complete actions that require Registry connections such as: Domain name registrations, renewals, transfers, name server modifications, contact modifications etc.
Please note that this will have no impact on the resolution / working of your already registered domain names.
Efforts are underway to get the issue resolved at the earliest.
Thanks for your understanding and support,
Internet Solutions HK team
