DNS Diagnostic: Update on the ATT DNS error

August 15, 2012-The ATT DNS outage demonstrates the importance of real-time root cause diagnostics when monitoring Internet services. Intermittent ATT DNS errors were first detected at 5:23 AM PST by Dotcom-Monitor a full hour before AT&T reported the issue. The Dotcom-Monitor Minnesota node noted the issue and captured a diagnostic DNS trace at the time of error. Non-clients of Dotcom-Monitor can use a free DNS trace tool here to test if their domain is affected by selecting Trace Style “DNS”.
