Error message for last page of long thread

When I try to click on the 5th page of the “When an intruder breaks in” thead in GD, I get the error message “failed to connect to the WWW server.” But I can get into the first 4 pages no problem.

I had the same error message trying to get into the end of another long thread from the index, but I was able to go to the firt page, and then page down to the end. No such luck on this thread.

Any idea why this is?
