About one morning out of every three, when I start my computer and go to IAP first (which is where I nearly always go first), I get the message 404 error, page not found. Sometimes as I continue to try, the message converts to "no site configured at that address".
A strategy that usually works is to run a Yahoo or Google search for "Penturners.org". Of course, both search engines find IAP. So, I can click on the link in the search and IAP will come up.
I have no idea why this happens. But the search tactic has worked every time, so far.
Hope this helps!!
