Hi, Some of our customers (BKK Fiber is an ISP) are having problems connecting to Web-services (TCP port 80) hosted by XO/Concentric. tcpdump shows that no packets are returned. Ping and connection to the SMTP-service (TCP port 25) on the Webserver hosts are fine. The problem seem to be limited to customers within a certain /17 allocated to us. I have tried Customer Care to no help. Has anybody else experienced the same with XO/Conecentric? Does anybody have contact information to Concentric operations? Kind Regards, Knut A.
