We are set up to use the IRIS Portal but when we log in it directs us to a web address of la.www4.irs.gov/irportal/ and a "Loading..." message appears and nothing else.  I've sat here for 30 minutes waiting for it to load and nothing.  Has anyone else had this problem?  I've tried calling the IRIS Portal support and the automated message says they are too busy to answer so call again later.
