We are going to migrate our data center in Hong Kong to a new infrastructure.
The new infrastructure is already available, and migration of traffic to the new data center will start on September 23rd.
The Hong Kong data center will be shut down on October 1st, 2020.
During the migration we will publish the IP addresses of the new cloud based data center and gradually change our DNS records so that traffic is routed away from the Hong Kong data center. At the end of the migration phase our data center in Hong Kong will be removed from DNS. You should see no noticeable impact on your service since the service will be seamlessly provided by the other Cyren data centers.
As part of the migration the IP addresses providing Cyren services will change. This change should be transparent to most customers using the data center in Hong Kong as Cyren client will automatically resolve to the new IPs closest to the client. In cases where customers use IP addresses instead of DNS resolving of the ServerAddress, and in cases where there are firewall restrictions for connections between the Cyren engine and the Cyren data centers, the IP addresses should be updated according to the information below.
