Architecture update

Previous week I've deployed a new version of DNSInspect.com which brings a new asynchronous architecture based on EventMachine which makes DNS reports really fast (on average ~7 seconds/report). Now most of delay is produced by mail servers and its RBL checks, I still need to make some fine tunings.

While working on this release I've learned a few things:

• Event-driven programming is hard, it's very easy to lock the entire process while waiting for event/condition that will never happen :)
• Extending Ruby with C is fun
• Starbucks may not have the best coffee, but it's a great way to escape from daily routine (warm ambiance, free WiFi and AC Power included)

Changes:

• Asynchronous architecture: checks are executed in parallel which leads to faster reports
• IDN (Internationalized Domain Names) support: Example reports:
  • Gartenmöbel.de - ”garden furniture” in German
  • 网站目录.com - Chinese
  • 스타벅스코리아.com - Starbucks Korea
  • аромат.com - Russian Shop
• TLD DNS reports: Example TLD reports
  • .com
  • .travel
  • .fr
  • .ly
  • .cz
  • .ru

DomainKeys checks where removed as everyone is migrating to it's successor DKIM (no DKIM checks right now).
