seconds before attempting to connect to the third party system. Once it tries to connect to
the third party system, the response time is only about 6 - 10 seconds which is normal. It
does not seem to be an issue at the third party's end as the response time is quick once we
get connected.

How does your code connect to the 3rd party? There are libraries that
do this, please elaborate which you use. I recall using one, and it
had a limit on the number of concurrent connections to a 3rd party.
Perhaps you hit this limit? How many connections are you talking about
when the problem occurs - 10s, 100s, 1000s or more?
