noise from a mozilla IT/Operations wrangler
During the past two Firefox releases (2.0.0.5 and 2.0.0.6) I’ve been running an dual-stake ipv4/ipv6 accessible download server. This box was serving Firefox updates and was part of releases.mozilla.org. I thought I could use traffic numbers to help justify a native ipv6 Internet connection. Here’s what ipv4 traffic looked like during a one week period… Read more
This isn’t necessarily Mozilla related but after spending a month on and off trying to get an IPSEC VPN up between a Cisco IOS router and a Juniper Netscreen SSG5 and finding very little help online, I figured I might as well document it here for others to find (myself, for instance, or, hey Google… Read more
If you’re ipv6 enabled, stuff the following into your hosts file and let me know how it goes. 2620:0:330:5::10 www.mozilla.com 2620:0:330:5::11 www.mozilla.org 2620:0:330:5::31 addons.mozilla.org It might even be faster (since you’re probably the only one using those machines)!

This whole saga’s been detailed elsewhere (and here and here and here). The Good (and the graphs) Last time, I rolled back when Europe… Read more
Nearly a month after the first attempt to get AMO (addons.mozilla.org) served out of Amterdam as well as San Jose failed, we’re ready to try again! I finally got the replacement hardware (Netscaler 9000s) in Amsterdam up this morning. During our Tuesday night maintenance window I’ll be switching DNS. For those late to this saga,… Read more
The 6bone is dead. Long live IPv6. (Don’t know what IPv6 is?) I’m no stranger to v6 – I played with it years ago while at 3Com (hi Cindy!) and actually deployed it natively, along with an automatic 6to4 tunnel relay, at the last ISP I worked at. However, I think I was on the… Read more
We run our web farm behind a pair of Citrix Netscalers in both San Jose and Amsterdam. What really hits these boxes hard is the SSL offloaded traffic and in certain instances has caused the Netscalers to fall over on themselves. Right now our setup looks like: (Pardon the shapes, it’s what I have to… Read more
