VPS Upgrade

As I’ve mentioned before, my blog is hosted on a VPS at Linode. Just under 3 years ago, I moved to my current VPS in their Newark DC to take advantage of their native IPv6 support. I’ve now moved within Linode again, this time to take advantage of their awesome free upgrades.

$20/month gets you a 2GB Xen VM backed by enterprise-grade SSDs, Ivy Bridge Xeons, and a 40Gbps backbone. Think that 40Gbps is going to waste? Think again. I downloaded a 100MB test file from Cachefly in 1.2 seconds. That’s 85.5 MB/s. Consider my mind blown.

I’ve been a Linode customer since 2009, and have probably had about 3 outages in the 5 years. All have been short, and have had good explanations with great communication from the Linode staff. There may be cheaper options out there, but I care about uptime and infrastructure, and Linode makes the necessary investments there.

Full ApacheBench tests for my old and new hardware are below.
