Some of you are already aware that the U. S. Government Shutdown has affected some of its websites as of Tuesday, Oct. 1, 2013. The USA.gov website is surprisingly vague on the exact websites involved in the web portion of the shutdown but gives some directions. Even more surprising is that USA.gov states it is "Government made easy". Well, a little online searching was still required. The USA.gov shutdown web page is the opening photo in this list. Other screen image captures of some of the affected websites will follow - but the copyright logos for those agencies are removed or obscured.
If you try to visit the NASA.gov website during the US Government Shutdown you should get this notice from Notice.USA.gov (1). Meaning, you can't visit the NASA website at all in this time!
If you try to visit the SNAP* (Supplemental Nutrition Assistance Program - also known as "Foodstamps") website you will be greeted with this notice from the USDA.gov (2). (USDA logo not removed as this page should be automatically removed after the shutdown.) Oct. 17, 2013 back online.
The CBP (Customs and Border Protection) website (3) – a site that should be regarded as "essential"? - will not be "actively managed" during the US Government Shutdown.
The CDC.gov* (Centers for Disease Control and Prevention) website (4) has also posted that funding has lapsed during the Government Shutdown. This website should be "essential" as it usually takes transactions on important health information of an immediate nature. Therefore, some of the CDC website functions will be excepted from the shutdown. Oct. 17, 2013 placed notice for employees to return to work.
You should be able to access the Veteran's Administration website as it is an apparent exception during the Government Shutdown. However, they do post a list of toll-free numbers (5) if you should need to make another contact.
The EPA.gov *(Environmental Protection Agency - copyrighted logo removed) website (6) will not be updated until the federal government reopens. Oct. 17, 2013 federal government reopen message now removed.
Due to the lapse in federal funding during the Government Shutdown the NIH.gov (National Institutes of Health) may not be updated (7) in that time.
During the Government Shutdown a large number of Social Security services should still be available. (Website not pictured.)
The "in-the-news" website of the NSA.gov is still available at this time and an apparent exception to the shutdown.
The Healthcare.gov website* (not pictured) is an exception that has avoided the "official shutdown" - though state insurance sites may have been knocked offline due to early overwhelming demand for its services. Thus the demand disproves the large political squabble over the Government Shutdown. Oct. 17, 2013 - may be experiencing account set-up issues.
