DNS issue in Cyren Data Centers
Incident Report for Cyren Cloud
Resolved
Due to a human error while updating the Geo IP configuration file most Cyren DNS servers failed to restart. At the time of the configuration change a partial validation was performed and the error about incorrect configuration was missed.
The Cyren DNS servers in our new data center in Frankfurt, Germany, were not affected and continued to serve DNS requests. Requests to all other Cyren DNS servers resulted in errors. Due to the DNS caching mechanism we cannot access the spread and impact of the issue on our customers.

The issue started at 14:16 UTC and was resolved by 15:40 UTC.
