Math, when 2 equals .2

In my last post I talked about a 2mW user.  Specifically I said:
5. Or, with roughly 250 million Firefox users, 50kW is 2 milliwatts/user (or 144Wh/month).

I haven’t stopped thinking about that number as a metric of measuring efficiency or how much power it takes to do work (provide services) for some number of Firefox users.  [...]

The power of Mozilla = .2mW/user

We talk a lot about Data.  It’s a fundamental component of Mozilla’s 2010 Goals, second only to Mozilla’s role as a centerpiece of the Internet.  In September, Mitchell talked about “usage data.”
IT, and especially Operations, collects of a lot of Usage Data. Most of this Usage Data is trended and used in capacity planning [...]

More traffic analysis with NetFlow

I’ve been working on a couple capacity planning projects and have been knee deep in bandwidth metrics. That, combined with turning up Level3 yesterday got me looking more into where that bandwidth is coming from (and Reed asked).
The first chart shows a breakdown by protocol. Shouldn’t be any surprise that 82% of Mozilla’s [...]

Level3, post BGP turn up

Derek turned up BGP peering with Level3 this morning out of San Jose (this was supposed to be part of last night’s maintenance but he ran into turn up problems on Level3’s side).

We’ve grown (bandwidth-wise) to the extent that having two transit providers wasn’t sufficient. Should either fail, I wouldn’t have felt comfortable [...]

Where is my Mozilla Firefox Infectious art?

My pleas to Mary have gone unheeded.  Where is my Mozilla Firefox themed Infectious artwork?
(Yes, this is a desperate plea to the community to come to my aid.)

Switch IOS Upgrade Post-Mortem

Last night Derek attempted to upgrade IOS on core1 & core2 to pickup software support for Cisco’s ACE module.
We ran into several issues and postponed the upgrade on core2 until those issues are resolved.

The switch’s Compact Flash cards weren’t formatted in a format that rommon (the low level boot loader) could read and the switch [...]

Uptime

I’m fairly conservative when it comes to upgrading switches. I generally only upgrade to pick up security fixes. It’s rare that I’ll upgrade just to stay current.
Tonight’s one of those rare exceptions. Derek is upgrading both core1 and core2 to pickup software support for Cisco’s ACE module. We’re planning on using [...]

My face is cold

NSID 2008 had to come to an early close for me today. I leave Monday for my sister’s wedding in Chicagoland and while I would have loved to hold out till the end of the month or even a few more days, that just wasn’t realistic (something about looking presentable).
You could argue I could [...]

I am outraged!

I can not understand why Ken Kovash is not on The Periodic Table of Awesomenes.
