Between August 08 2008 18:00GMT and August 09 2008 03:00GMT, GrabPERF had a network-related outage at the hosting facility.
Many thanks to the Technorati team for working hard to resolve this complex issue, which eventually turned out to be a loose fiber-cable.
Data from the time period has been cut, so no one’s stats should be affected.

Yes, it’s YATPBP (Yet Another Twitter Performance Blog Post).
About 10 days ago, I turned GrabPERF loose on Twitter. Now before you accuse this of crippling the service and bringing it to its knees, realize that GrabPERF simply requests a document over HTTP about two times a minute. No additional requests are made for images and [...]

I know that I have been bad at blogging news about GrabPERF, but today there is some. In the last two weeks, we have added two measurement locations: Washington DC AOL and Argentina LaNacion.
Thanks to Carson Evans of AOL, and Jose Falvo and Leonardo Lancellotta of LaNacion for helping out with the installation process.

Look ma: Macy’s is already too busy.

Yeah. Let the fun begin.
Technorati: GrabPERF “Black Friday” “Web Performance” “Macy’s”

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 [...]

GrabPERF returned to service at approximately 17:30 GMT (13:30 EDT — 10:30 PDT) September 20 2007. The database server was on all night, but an esoteric choice of primary interfaces (i.e. the least obvious one!) meant that it was taking to empty space.
Have fun and enjoy the data!

GrabPERF has been offline all day, and will likely be offline for the remainder of the day as Technorati relocates the servers to their new datacenter.
Sorry for the inconvenience.

Had an on-site meeting with Dorion Carroll and the Technorati team. We discussed some ways to extend and expand the GrabPERF infrastructure, and improve the measurement gathering.
Look for changes in the next 6 months that could radically improve the system you know and love!

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 [...]
