I am an artist with enough php to be dangerous who is fighting a colo server
that was making a cURL connection and suddenly will not. No one changed anything
on the server or the script during the time it began to fail.

The server runs Linux and under my root control (someone configured it for me).
The cURL information on the phpinfo page is libcurl/7.12.1 OpenSSL/0.9.7f
zlib/1.2.2.2 libidn/0.5.15.

The original script was to connect to the authorize.net gateway in ssl.

I've conducted numerous test cURL connections with the following results:

From SSL to SSL, from Public to Public it works everywhere BUT the colo.
From SSL to Public OR Public to SSL it never works -- reasonable.

The test form is at:
<https://www.expressionsinc.com/test/test.php>

One that works is at:
<https://yak.he.net/~hprc/test.php>

Curl Response script:
<https://cyclone.he.net/~artdude/curlresponse.php>

I've also done tests within the domain and within domains on the same server,
all with the same results. If it originates on the colo server it will not
connect.

My speculation:
1. There is some server configuration that expired or got wacked.
2. There is something in the data center firewall or dns (or something I don't
know about) that is preventing the connection.

Any ideas?
BTW: I know just enough ssh/telnet commands to get onto the server and roam
around a bit. My mac and I are happy to have Mr. Job's GUI.
