Rant: 100%

Posted by Philippe on October 24, 2006

What does 100% mean to you?

Does it mean:

  1. 20 out of 24 hours of uptime?
  2. 22 out of 24 hours of uptime?
  3. 23.8 out of 24 hours of uptime?
  4. 24 out of 24 hours of uptime? HINT: This is the answer.

Seriously! If you are a service provider and you have a 100% network and power uptime guarantee, are hosting corporate customers, and then have a 4 hour outage due to power on Saturday and then another 3 hour outage on Monday … you don’t have a 100% network and power uptime!

I’m sure that that’s surprising to many people who read this, but … come on! First off, 100% network and power uptime providers should have the following:

  1. Backup Power Systems
  2. Backup Network Providers
  3. Failsafe switches

If you don’t have those? Don’t guarantee 100%. If you want to guarantee 100% … get them.

    Not to knock the provider you’re talking about, but who can provide 100% uptime? I’ve never seen anything with 99% uptime, because there are times where reboots have to happen, the aforementioned power outages happen, when no one pays attention and something dies, etc. Granted, you’ll never see a provider say, “64% uptime guaranteed or your money back, if our accounting system is working!”, but I think it foolish someone would advertise anything more than 99.9% uptime.

    The 100% uptime guarantee offered by this specific provider is specific to network and power, nothing else. Scheduled maintanance doesn’t count, any pre-notified downtime doesn’t count, etc. I think that offering 100% uptime with purely network and power should be possible.

    Dual backbone providers into your primarily switches with multiple failover points.

    Dual power systems.

    Overall, sure. Its not something that is going to happen all the time — on a monthly basis, however, it should be possible to end up with 100% if you set up your systems correctly. Sure, there may be times that a major event occurs and everything fails, multiple OC12s simply drop, the city cuts all power to the building at the same time as they sever the fiber … but these should be significant exceptions.

    Technically, it applies to 100% connection EXCEPT during scheduled maintenance.
