“VerizonMath” Original Recording
One of my favorite Internet relics is VerizonMath. If you aren't familiar with it, it's about a guy who called Verizon asking about roaming-data charges on his cell phone and got multiple responses that confused 0.002 dollars and 0.002 cents. He posted a recording of one of his calls online.
The blog is still up as of 5 August 2016 with a repost of the original phone-call recording. However, the first post has the real original recording, which was hosted on Putfile, which is now dead.
Fortunately, the file was mirrored on VerizonMath.com, but after digging through the Wayback Machine, I found this archived copy (which you can access from the source code of this archived Web page; it's in the embed element). For added robustness, I've also published it on IPFS as QmZ8u641rStq4ND9AftRBJdoaf4bs9F2rhpRpnqVh9k8ad. (For a brief introduction to IPFS, read "HTTP is obsolete. It's time for the distributed, permanent web".)
Many thanks to the Internet Archive for preserving all sorts of digital information.
