Cloud SWG: DNS Errors for .de Domains

Monitoring
Monitoring

We are seeing DNS failure rate back to normal. Based on our tests, the DNS queries are working fine for the .de hostnames.

We will now monitor the service for stability and provide updates as soon as new information becomes available.

Investigating

We are seeing a high rate of DNS errors for .de domain. As per our initial investigation, It looks like the owners of the .de domain are investigating a faulty DNSSEC configuration.

This may impact CloudSWG service customers because DNSSEC is required by the service. Customers are likely to see the following exception pages for requests to websites in the .de domain:

  • "dns_lookup_failure" or
  • "dns_server_failure"

Note that there is no impact to protection services and all other aspects of Cloud SWG service remain operational. We will provide further information as new information becomes available.
