Our free servers are under a large DDoS attack. We work all day to mitigate it.
Thank you for the patience.
UPDATE: The attack is against cdkjq.com that points to our servers. DNS zone is already suspended. The owner of this domain name doesn't answer of the requests to remove our servers from the domain name.
UPDATE [2013-06-02 9:00 CET]: NS2 and NS4 are back and sync. We work to get all free servers back.
UPDATE [2013-06-02 9:30 CET]: NS1 is back and sync.
UPDATE [2013-06-02 20:00 CET]: NS3 is back and sync.
