No, it is not your computer or your internet connection. Nor anything you clicked.
Ancestry.com and many of the websites it owns and operates have had a technical problem today and went down sometime before 4 p.m. EDST, Monday, June 16, 2014.
Ancestry.com is working on the problem but has not stated when the sites will be back up.
Keep an eye on the situation by checking Ancestry.com's FaceBook page for the latest information. (No, you don't have to be a Facebook member to see this part of the main page and the comments.) You can also check the site at the Is it down right now website.
When Ancestry.com gets back up and running, I'll let you all know.
