How do you manage a lot of log files from a lot of hosts?

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

Where in the world is AMO?

After a week or so of testing, we’re ready to flip the switch on getting addons.mozilla.org to be served out of Amsterdam as well as San Jose.

Where’s Mozilla traffic going?

One of our objectives for this year was to get a better trending of network traffic and flows for capacity planning, colo planning and attack mitigation. The NetFlow tool we’re using also allows me to run a report of top destination ASNs, or networks we send the most amount of traffic to as well as… Read more
