Internet works for some customers and doesn't work for others. I am wondering if customers in trouble are not using any king of Internet acceleration/cache application which modifies the DF bit in TCP. Before focusing on TCP, I will check the following - download a large file using tftp - download the same file using ftp -what customers in trouble have in common?
Sorry for not being able to provide a straight answer to your question, if you provide more details, it will be easy to find what the problem is.

I work with an ISP as network engineer and some of my customers are connected to my Internet backbone network using BGP op IGP for some of them. However, some of the customers are complaining that the can't get to some web site. But when trying to change the MTU at the end user workstation, the connectivity to all the site is OK. I don't know the solution and am wondering how to change the MTU on my router's Ethernet interface without asking the customer to change the MTU on all the worksattion ? Traceroutes shows that packets are lost beyong my provider's backbone. Is there something my Internet provider should do in other to let my customer have access to all the web sites ? Thanks !
