This morning’s DOS attack was directed against ns1.easydns.com and is an ongoing event. Some upstream networks from our Q9 datacenter (Toronto) are enacting counter-measures which will render NS1 unreachable to users on the other side of those networks (examples are Teleglobe and Cogent).
The rest of the nameservers (Miami, Phoenix, Texas, Toronto2 and London, UK) are unaffected, overall DNS availability was not affected by this attack, however email and web forwarding was impacted during the initial attack phase. Please note that no email was lost, only delayed and email forwarding times returned to normal very quickly.
More as it comes in.
