22 Aug 2007My system has a daily job to collect and aggregate the IP Blocks distributed by the five registrars into a single database, and then provide high-level WHOIS information for this data. If you want to try this yourself, the interface here.
On an extremely irregular basis, I aggregate the statistics from this data, and present it [...]
My side project, GrabPERF, is looking for a few good measurement locations.
Right now, there are only five measurement locations, two of which are in my basement, on my personal Internet connection. I am hoping, through this pledge drive, to find a number of additional locations. Areas desperately needed include:
East Coast, USA
West Coast, USA
Midwest, USA
UK
Asia-Pac
Southeast Asia
Australia [...]

26 Sep 2006I was futzing around with my WRT54G(L) last night and did something wrong. I thought I had bricked the damn thing. Much cursing and swearing ensued as I put a BEFSX41 on the front-end of the network (I have three of these; don’t ask why) and wandered upstairs with the lump of black and blue [...]

26 May 2006We are in the process of relocating the GrabPERF servers to new IP addresses. You may experience some weirdness as the DNS propagates, but this should die down in a couple of days.
If you do hit an issue, you can still reach the server at http://208.66.64.70/.

11 Aug 2005Today, by special delivery, I got notice that FIOS is available at my house.
I called Comcast and asked how they were going to match this offer. They offered me $29.95/mo. for 6 months.
Now, because of my unique situation (i.e., requiring a semi-permamnent IP address to allow people to access my servers), I may be stuck [...]
