  1. Akamai “War” Stories Bruce Maggs

  2. Akamai’s First Network Connection We moved into our offices at 201 Broadway at midnight, December 1, 1998, and built our first cluster that night. An important potential investor was coming to visit on December 2. But our Internet service provider didn’t show up on December 1! We had to engineer a solution!

  3. David is a Night Owl • Your servers aren’t responding! • Why don’t you support half-closed connections? • Why don’t you support “transactional” TCP? • (Why would transactional TCP be bad for Akamai?)

  4. Steve can’t see the new Powerbook • Steve’s assistant Eddie explains the problem • I spend all night poring through the logs • Eddie sneaks into Steve’s office • Mystery solved

  5. The Dreaded Double Header • http://images.xyz.com/logo.gif - customer has delegated images.xyz.com to Akamai, registered image server • http://images.xyz.com/images.xyz.com/logo.gif - didn’t work for Dave, but worked for me! • Akamai server strips off first header, sends GET /images.xyz.com/logo.gif to customer image server • 5 of 8 customer image servers had been patched to ignore /images.xyz.com

  6. The “Magg Syndrome” • We “hijack” a customer’s site? • I become the most hated person on the Internet • We isolate the problem (nine months of work) • Nobody cares?

  7. Don’t do this at home • Irate end user threatens to go to police • Akamai is attacking my home system! • It’s in the logs. • It all began in a Yahoo! chat room • Have your lawyers call our lawyers

  8. BIND Miseries • Open-source DNS server code • Messy, buggy implementations • Our customers still run old versions! • BIND 4.8 TTL issue • Refresh attempt when 15 minutes left • Success if new list of IP’s overlaps with old list of IP’s • Otherwise, refuse to resolve for next 15 minutes!
