For approximately an hour today, from 10AM - 11AM Eastern, the Blackhole and Client API were intermittently inaccessible.
During this time, the impacts were:
1) Users would experience long response times and timeouts when visiting blocked domains. They would not see a block page returned by the Blackhole.
2) DNSWatchGO clients would be unprotected. Note, DNSWatchGO is currently in beta.
3) All other services, including being protected via our DNS resolvers, were not impacted.
We apologize for any inconvenience. Please contact technical support with any questions.
