OVH server not getting response to outgoing request
I've a strange problem since today. My OVH servers in Singapore and Sydney don't receive the http response to a request they sent to another non-OVH server.
Tried with wget, etc. The response server sents out the data fine with HTTP 200 code, but it's never received at the requesting OVH end.
Could it be that their ddos protection got crazy and blocking the incoming response to the outgoing request?
Ping and mtr show no problems in both directions.
At OVH I only found this: http://travaux.ovh.net/?do=details&id=46399& and suspect than sth. is still wrong w/ their anti-ddos mitigation.
