We received a report yesterday about a DDoS against Joker.com's DNS servers. Thanks for the report! From the site "Joker.com currently experiences massive distributed denial of service attacks against nameservers.
This affects DNS resolution of Joker.com itself, and also domains which make use of Joker.com nameservers.
We are very sorry for this issue, but we are working hard for a permanent solution.
Thank you for your understanding".
