MTU is a property of a link, not of packets; I was suggesting that perhaps a change occurred in the settings of a router through which packets are going. This is probably much ado about nothing, but it is at least easy to test, e.g., by bringing up the interface with a lower MTU, and seeing if the problem goes away. Years ago I had to mess with this to accomodate a (possibly broken) DSL or ppp interface. Some of the symptoms described in this thread sounded familiar, e.g., sometimes things work great, other times slow or not at all.
