Suddenly I get the following error when trying to access my site

Error in ISAPI_Rewrite helper ISAPI extension.

12030 - The connection with the server was terminated abnormally

File: .\rwhelper.cpp, Line: 1290.

Anyone know anything about how to resolve this? It was working fine yesterday, and I've made no changes since then. Any information that can be provided is appreciated.

Nevermind, apparently this is a problem involving a global outage with my host.
