The .tel registry emailed all domain name registrants directly last month to announce some important changes to the hosting of .tel domain names. Please see a copy of the .tel communication here.
On the 13th March .tel will switch off their old hosting platform so everyone that has a .tel domain name must make sure they have uploaded any content to the new platform via the login they have provided. Unfortunately, any content on the old platform will be lost after 13th March 2017.
If you have a .tel domain name and have any questions, the .tel registry has asked customers to contact them directly at firstname.lastname@example.org
