Computerworld (a so-so publication) reported that a major hosting company was severely affected by an explosion. You’ve all heard ThePlanet.com. That’s right, they were affected by an explosion.
The printable version of the story can be found here.
What’s interesting is that ThePlanet.com bills itself as a high-end hosting provider and yet over 9000 of its servers at the facility were affected.
So what is a Tier 4 Host? Is Tier 4 better than Tier 1? And what about a Tier 1 ISP, versus a Tier 4 ISP? Are they the same? Guess what, they are not.
For Hosting companies, being Tier 4 is best. See this article. Essentially, a Tier 4 host should have capabilities above and beyond its competitors.
For ISPs, being Tier 1 is best. See Wikipedia. A summary is as follows:
- Tier 1 – A network that can reach every other network on the Internet without purchasing IP transit.
- Tier 2 – A network that peers with some networks, but still purchases IP transit to reach at least some portion of the Internet.
- Tier 3 – A network that solely purchases transit from other networks to reach the Internet.
So the next time someone says we’re Tier 1, think twice. What’s best? A Tier 4 Host, with multiple Tier 1 ISP hookups. And always Google to make sure they didn’t have a fiasco like ThePlanet.com did recently.
