I'll try that with the tablets and phones. The Samsung was acting funky. My desktops delete all the cookies frequently so I don't notice it.Thanks Chewy. I had to do the same with deleting cookies. For those who may use a mobile device or tablet, you'll likely have to do the same on those devices also. I was having strange behavior on on my phone until I deleted the cookies.
Thanks for the suggestions. I setup an account with uptimerobot.com to give them a try. That will give me some indication if things aren't working here. I have another server located outside of this environment that I can use as a status page. Whenever someone is experiencing downtime at sf, you can check the site health page and see if the server is unreachable.
