The system that hosts this site has been experiencing intermittent problems over the past two days.  I’ve reported the problem and I hope that steps are taken to keep this from happening again.  Unfortunately, the last time I reported it the problem had been corrected by the time they got around to my support request and I just got a note saying that the site loaded fine.  This time I did my own problem determination (and some research) and sent them more info.  Let’s hope that something comes of it.  This would mark the fifth time it has happened and my patience is beginning to wear thin.
