April 2, 2013 – Network Solutions DNS, a major provider of domain name server (DNS) services, experienced an issue over the Mar 30-31, 2013 weekend resulting in many websites, including websites owned by Dotcom-Monitor clients, having website DNS time out errors. Intermittent Network Solution DNS issues were noted late afternoon and evening hours on March 29. Dotcom-Monitor then began tracking consistent DNS time out errors involving Network Solutions DNS servers early on Saturday morning, March 30, 2013. The Network Solutions DNS servers involved were NS22.WORLDNIC.COM (188.8.131.52) and NS21.WORLDNIC.COM (184.108.40.206).
Dotcom-Monitor System Status
On Feb. 13, 11:05 am CST a server hardware issue resulted in a gap in monitoring for approximately seven minutes (11:05 am CST – 11:12 am CST).
UltraDNS Outage: We are aware that some websites and reports may indicate an UltraDNS outage on January 28, 2013. We have verified that UltraDNS did have a short DNS issue. We will continue to monitor the situation, although it now appears to be resolved.
Starting at around 06:00 AM CST, July 23, 2012 Dotcom-Monitor began to detect a higher than usual number of DNS-related errors. The errors were sporadic and happening in bursts every couple of hours.
We are still looking for a root cause, but we believe issue started with a DDoS on Zerigo DNS services. We have a large number of our clients using Zerigo for their DNS hosting. Zerigo took their servers down due to the DDoS DNS this morning.
Dotcom-Monitor is researching internal and external systems for clarification regarding reported DNS and other issues. We will update with additional details today.
