Subject: Zerigo DNS Outage Explanation
To: srainsdon AT nunetnetworks.net


Dear Zerigo Managed DNS Subscriber,

On July 22nd at 8:30 PM PDT our global network of Zerigo nameservers
became the target of a large-scale DDoS attack, saturating bandwidth
in multiple data centers. This impacted availability of four of our
six global nameservers as well as our management portal. We
immediately applied our DDoS mitigation measures, and worked
continuously with our carriers to restore service availability.
Service was fully restored for all global nameservers, except Dallas
and UK, at 12:50 PM PDT on July 23. Our Dallas and UK nameservers were
brought back online at 8:00 PM PDT on July 23.

These kinds of malicious attacks are not new, however they are
becoming more sophisticated. While no amount of protective measures
are guaranteed to be 100% sufficient, we are implementing additional
safeguards to protect the service from future attacks of this
magnitude.

We sincerely apologize for the issues caused by this attack.

Sincerely,

The Zerigo Support Team
