Sounds like:
(a) DNS lookup problems, or
(b) A close relative of your second problem.

This is a persistent connection bug. The most common cause is something
adding HTML code to a web-page without updating the content-length
correctly. Most browsers try to hide little details like this (by
continuing to read until data stops coming) but it shows up if there's a
delay in transmission after the number of bytes specified in the
content-length has been sent to the browser.

Check: is something inserting a navigation-bar or advertising banner at
the top or bottom of pages? If so, then that's your culprit. I, myself,
have stuff that adds to in-transit HTML, and I made this self-same
mistake with forgetting to update the content-length headers correctly.
