Here's what I get from Firefox trying to fetch that page (red text added):

This Connection is Untrusted

You have asked Firefox to connect securely to acc.dau.mil, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

What Should I Do?

If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.Get me out of here!

Technical Details

acc.dau.mil uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer)
I Understand the Risks

They are likely using a self-signed certificate, which means the connection is secure, but the identity of the server is unproven (i.e., it might be the bank or it my be Ivan, here, but eavesdroppers can't read it).

I would just ignore it. Unless you were trying to communicate secure information to the site in question (e.g., it's your bank or broker), you should be entertained, not worried.
