Portland Hikers' site has been having some problems lately, especially evenings and weekends when a lot of folks are on. It's a shared server, so it may not necessarily be a PH problem. I've never gotten the "Not Found" message until today. I usually check the site twice daily and had no problems yesterday.
We had high winds slam in here about 4 am and quite a few places lost power, so that might have something to do with the problems today.
If Jerry comes on (he's a PH moderator), he may be able to enlighten us. Unless, of course, he is one of those who lost power!
