The primary goal of documentation is not to ensure perpetual access to a source but to verify the publication facts of the version you consulted. Thus it is acceptable to cite the original version with the defunct URL:

Bluestone, Gabrielle. “Three Jailed in Myanmar for Posting Image of a Buddha Wearing Headphones.” Gawker, 19 Mar. 2015,  gawker.com/three-jailed-in-myanmar-for-posting-image-of-a-buddha-w-1692317287.    

If you know when you were last able to access the page, include that date in the final supplemental element of your entry with the label “Accessed.” For more information about including an access date, see 5.111 of the ninth edition of the handbook.

If you subsequently fact-check your work using an archiving website such as Wayback Machine, however, we recommend that you cite the new version of the page that you have consulted; be sure to include the name of the original site in your entry:

Bluestone, Gabrielle. “Three Jailed in Myanmar for Posting Image of a Buddha Wearing Headphones.” Gawker, 19 Mar. 2015. Wayback Machine, web.archive.org/web/20150319101001/http://gawker.com/three-jailed-in-myanmar-for-posting-image-of-a-buddha-w-1692317287.
