Knut,

A couple of possible reasons that make perfect sense. 

First, a number of ISPs intercept port 80 traffic (http) for advertising or cache purposes but don’t do the same for the ftp port; if the cache or advertising machine has DNS issues, so will anything downstream. 

Second, ftp and http may point to different IP addresses — for example my file and web servers are different machines so are on different addresses. Added to which they have different TTL values too.

I hope this helps.

Regards
Andy, G8TQH
