I contacted DigiChat about it, and they're asking anyone that experiences a problem trying to get in if they could run a traceroute to their server: host5.digichat.com. They think there may be a problem with international connections possibly being blocked at certain IPs.
Here are a couple quick links on how to run a traceroute...

Thanks in advance for any help troubleshooting this problem.
