As of today, June 17, 2014, Ancestry.com is still experiencing outages on its various websites. It is likely at times today, you will find the websites operating and at other times not operating.
Another blogger, who knows some people inside Ancestry.com, suspects that the problem is that there is a Denial of Service (DOS or DDOS) attack taking place on Ancestry.com's servers. This has NOT been confirmed by Ancestry.com itself as of this post.
Note: I've included a link to Wikipedia's explanation of a Denial of Service attack. Essentially, this is being done, for whatever reason, to make the service unavailable to it intended users.
Continue to check Ancestry's Facebook page for the website's status, or check on the site using Is it down right now. When the crisis is over I'll let you all know.
In the meantime, if you want to do genealogy (instead of using this opportunity to do some house or yard work) try another website or do one of those "not so fun" genealogy tasks we keep avoiding like organize our papers. Take this time to scan some pictures or documents (that are not digitized out there on the internet). Or, visit your local library.
See you soon at the Mt. Clemens Public Library!
