mon.itor.us, a service which also provides free Web performance measurement services, appears to be having a wee problem.

The most recent GrabPERF data on this site is available here. The issue may be corrected by the time you look at the data.
I don’t wish suffering like this on anyone. GrabPERF had it’s own 3-4 day outage [...]

It has been at least a year since I last updated everyone on the state of GrabPERF. That’s because for most of the last year, the system has been rolling along without a hitch or a major systemic change. The last major change to the agent code was alomost exactly a year ago, when I [...]

If you use GrabPERF on a regular basis, the somewhat flaky navigation method has become second nature to you. In fact, to circumvent some of the idiosyncrasies, you have probably bookmarked your favourite pages.
Yesterday, I broke your links.
When I redesigned GrabPERF in February 2006, I had just discover the require function in PHP, and decided [...]

A colleague of mine suggested that the Tour de France give up all pretense of being drug free, and embrace the performance-enhancing image it has developed so carefully over the last quarter century.
His idea was to have the racing teams sponsored by the major pharmaceutical firms, pitting one performance-enhancing approach against another, in a competition [...]

Netcraft noted that Yahoo encountered a bit of a headache today. So I fired up my handy-dandy little performance system and had a look.

Although for an organization and infrastructure the size of Yahoo’s this may have been a big event, in my experience, this was a "stuff happens on the Internet" sort of thing.
Move along [...]

This morning, I noticed that Gizmo has one more advantage over Skype: substantially better performance over slower/less optimal WiFi connections.
Skype is slowly getting the can from me. Sorry kids.

I have set up measurements to monitor the main pages of some of the world’s largest mobile phone providers.

US Providers
Canadian Providers
European Providers
AsiaPac / South Asia Providers

Just something to do on a rainy Sunday.

The client visit this week (and don’t expect too many details) was to MySpace. It is interesting to get an inside perspective on their performance challenges, as well as their beyond unique infrastructure.
I am bagged, and off to write up a document for another client.

Many thanks to Otis Gospodnetic of Simpy for putting me in contact with Benjamin Reitzammer. Benjamin has graciously set up the GrabPERF measurement script on his server in Zurich.
Now that the Europeans have a growing presence on the GrabPERF Network, we need some locations in the US and Asia-Pacific.

This morning, after months of increasing performance issues, and connectivity issues, I have retired the Boston Verizon measurement location. This location hosted 2 measurement agents.
The machines, hosted in my basement, are connected using Verizon FiOS, which has become increasingly flaky over the last couple of months. As well, the machines are 7 year old Pentium [...]
