We have brought up some new nameservers to replace old ones.
If you are using the names of the servers as provided in your welcome mail, then you do not need to change anything.
If you are using IP addresses then you will need to make the following changes
Change 22.214.171.124 to 126.96.36.199 (EU Nameservers)
Change 188.8.131.52 to 184.108.40.206 (US Nameservers)
The servers in Red are being retired as DNS servers from 31-Oct-2016
Another new European DNS Server is available 220.127.116.11
So the two DNS clusters are:
18.104.22.168 - Roubaix DataCentre 22.214.171.124 - Strasbourg DataCentre 126.96.36.199 - Gravelines DataCentre
Nameservers for the US
188.8.131.52 - Beauharnois DataCentre 1 184.108.40.206 - Beauharnois DataCentre 2
