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 […]
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)!
With little fanfare, we flipped the switch last night and started serving addons.mozilla.org out of both Amsterdam and San Jose. Took two tries and a hardware swap, but we got it!
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 started waking […]
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, take […]
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 […]
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 work […]
You use Splunk, of course! And for those that hadn’t noticed, the 3.0 beta went out yesterday. You should probably get it.
Update: Under their beta notes I see this: “Only the Firefox browser is supported in this beta. Support for IE will be added later.”
I won’t shed any tears over that
In an effort to redefine the meaning of “performance”, we turn them into a performance cluster (where slower is better).
As Boris Zbarsky said,
If the hardware is so fast that, say, the Date.now() resolution (or whatever perl module we use) is insufficient to accurately time the tests, then we have a problem.
This follows up to […]
Shortly before 12:30am PDT I had to roll back the DNS changes to AMO and serve it only out of San Jose. Around this time, Europe started coming online and pushed traffic loads up, exhausting the capabilities of the Netscalers in Amsterdam.
The Bad
Unfortunately when SSL transactions/second hit nearly 900 a second the CPU was […]
Pushed out the DNS changes to addons.mozilla.org about 36 minutes ago. Those of you on the other side of the planet should see much improved page load times.
