11. “Operator, Can you
connect me to drupal.org?”
• Most “free” DNS servers from your web
host are not very good
• Global “anycast” DNS servers are faster
and more reliable
• Affordable offerings from Rackspace
and Amazon (no excuses)
• Enterprise offerings from Dyn, UltraDNS

12. Go global with a CDN
• Site optimizations do not bring your
users any closer to your site.
• CDN caches your site pages & content
at the edge, closer to customers
• Bulk of content served from CDN
• Drupal CDN module makes integration
painless
