I have Earthlink DSL.  The DNS servers take a break every now and then.  
There are two servers, so I ping one and then the other and compare.  I don't 
know a lot about DNS but they seem to throttle every request you make - even 
if you "ping 222.111.55.2" for example, the DNS will look "222.111.555.2" up 
and you will take a delay.  Maybe the DNS is doing its maintenance updates 
when you are slowing down?  When you are in the slowdown mode, go to 
/etc/resolv.conf and comment out the DNS servers and add "search 
localdomain", then ping an outside IP address (outside your LAN).  If there's 
no slow down, then maybe the slowdown is coming from the DNS.
