Yesterday we had problems with our servers. As normal we have ~20 million request per day, yesterday we had over 2 billion requests. Because of this (and not only) problems we will make some changes:
1. NS3 as most stable server will be moved only for premium users. We will start new server in Germany (top location in European internet) as new NS3 server.
2. NS2 as most unstable server will be moved to another provider in different data center in USA.
The changes will be made in the next 30 days. The changes in 1 will not affect our service and you do not need to make changes in the domain zones configuration. The changes in point 2 will affect only zones with DNS branding, IP address of current NS2 server need to be changed with the new one. After the upgrade we will send mails to all premium users with instructions for configuration changes.
We apologize for the problems with our service. We work to make it better.
