Off topic I guess,
But MTU fragmentation (especially if the site operates under SSL) can
cause things like this - seen it before. SSL especially, is very
sensitive to fragmentation.
+1 on the MTU settings.
Firewall replacements and upgrades (known or unknown) are what I find
introduces issues like the one you are describing.

Hi,
Fair warning - not 100% PHP based question coming, but since it's almost
Friday, I thought I'd risk it.
My wife posed a question to me today for which I didn't have a very good
answer and thought I'd check the hive mind here. At work, she uses a
certain service to upload PDF files, until about 3 days ago this worked
well enough. However, in the past three days when she tries to upload
through the service she receives a variety of errors from 404 page not
found, to an unexpected error occurred, to the service is busy, or the
ever enjoyable endless spinning circle with nothing happening (at one
point she started an upload, went for lunch, came back to a meeting,
then on her way out for the evening forgot it was running to find it
still sitting spinning its wheels). These files are all typically under
1MB, so the entire process itself shouldn't, and until three days ago
didn't, take all that long.
She's tried to use the same service outside of work (on our home ISP as
well as two separate cell providers) and it functions as expected. So,
she's thinking something on her work network must have changed, but IT
isn't very interested in the matter. She has tried on several different
computers in the office, all producing the same result of the file not
uploading with one of the above mentioned errors.
I have run into a similar problem in the past with a Hospital client
that had an IT staff that seemed to enjoy randomly pressing buttons.
For awhile uploads would work, then one day - from within the office, no
go - outside the office everything ran as expected. Eventually the
problem sorted itself out, which leads me to believe some random setting
was possibly changed on the network. In such a situation, any pointers
on where an investigation may begin? In my wife's case, I'm not sure
its an option to ask IT what was changed three days ago as she works in
a public school system that all connects through a large central
office. But if she was able to pose the question a bit more
specifically, and the stars align themselves, perhaps an answer may be
found.
If this is a little too far into the OT realm, move along - these aren't
the droids you're looking for, and have a nice day :D Otherwise, thanks
in advance for any advice you may be able to offer.
-Tim
