VPS.NET Japan cloud test failure – Success!

[blackbirdpie url=”https://twitter.com/vpsnet/status/116838472219770880″]

Today at around 06:30 EDT, VPS.NET engineers did a test failure at their recently launched Japan cloud and it went really well!
No downtime, no data loss, nothing. Exactly as it should work. Kudos to the VPS.NET team! I really hope that they have found the perfect solution for their SANs and that they will begin rolling-out the new technology to their other SANs soon.

Below is the output of sar, about an hour and a half after the test. The lines that indicate that something was going on (i.e. the test failure) are highlighted.

VPS.NET Tokyo cloud launched

[blackbirdpie url=”https://twitter.com/vpsnet/status/113858818764570624″]

We are pleased to announce the new beta of our Japan cloud (Tokyo). We are offering old and new customers up to 9 beta nodes for free to test out the location.

Highlights include:
– The fastest, most technically advanced enterprise class SAN within all of our clouds
– Full support for Windows and Linux
– Full OnApp 2.2 support will be enabled during the beta
– Its Free!

VPS.NET just launched their Tokyo cloud today in beta. According to them, this new cloud features an all-new SAN deployment which will resolve issues like their recent (and not only) 50h downtime + customer data loss. SAN failures have been a major issue at VPS.NET during the last year and many customers who didn’t had their own backup strategy lost all their data because of file corruption after a SAN crash (hint: don’t rely on VPS.NET backups -unless R1Soft- and always have your own backup strategy!)

Stress testing WordPress on a single node VPS

Lately I’ve been trying to find a cheap close-to-perfect-but-not-so-difficult-to-setup solution for my personal blog. A kind of “set and forget” thing if you will.
Until now, my blog was running on a Dell Dual-Xeon /w 2GB RAM cPanel server (along with a few other sites) and was working pretty smooth. Based on pingdom’s full page test my blog needed 6-7 seconds to fully load which is kind of acceptable considering the theme, the twitter/flickr integration on the sidebar and the needed dns queries to contact facebook, google analytics and woopra servers.

Last night bestvpscloud from the VPS.NET forums pointed out to this script that installs nginx, php5, mysql, exim4 and wordpress on low-end VPS servers, and after reading the comments I got to this guy’s blog who also suggested adding the dotdeb.org repository and upgrade to PHP 5.3.
