The DDoS spam bot from hell (a suburb of China)

Happy new year everyone,

I'm back online to put out a fire. My inbox was full of alerts that the CPU on the server that runs the site was maxing out.

Well boys and girls, it turns out www.turnkeylinux.org has been under an escalating distributed denial of service attack that started about two weeks ago. To the best of my knowledge the site continued operating normally. We use a ton of caching. Did any of you notice a slowdown?

Mapping AWS data centers for fastest connection

Yes, that's 'fastest', not closest.

Background

A while back I published a blog post entitled Finding the closest data center using GeoIP and indexing, which described how we automatically determine the AWS regional data center to be used for storing encrypted server backups.

TurnKey 11.3 maintenance release - next stop Ubuntu 12.04!

Ho ho ho, happy holidays everyone! I know most of you are already shifting into holiday mode, so I'll keep it short and sweet.

We've just pushed out TurnKey 11.3 - the final maintenance release based on Ubuntu 10.04. The next release will be based on Ubuntu 12.04. We're already shifting into high gear for that. There will be surprises. Hopefully good ones!

New Hub feature: Cloud server monitoring

Ladies and gentle geeks, I'm proud to announce we've just pushed out 100% free basic server monitoring to all TurnKey Hub accounts. This should make it easier to keep tabs on the health and performance of your cloud servers. Existing Hub users don't need to do anything to enjoy this new feature. It just works.

A better server dashboard

As you can see in the screenshot below, the server dashboard now includes thumbnail graphs of CPU utilization, disk IO and network traffic for the last hour:
