Maybe not “Soooo big!” But still counting on bitly

[This was originally posted on August 13, 2011, but had to be “reconstructed” following the crash of a MySQL server at my Web hosting service.]

About this time last summer, I wrote three back-to-back posts about the URL-shortening service bit.ly, now routinely re-directed — how ironic! — to bitly.com and self-referenced as simply “bitly.” The posts were entitled “Soooo big!” Counting on bit.ly and were focused on estimating when bitly might run out of unique URLs:

‚óŹ Part I calculated that the available 62 characters (26 upper- and 26 lower-case letters, plus 10 digits), taken six-at-a-time with repetition allowed, yielded a pool of 62^6 = 56,800,235,584 unique hash strings available for assignment in URLs.
