The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

On T-1s, routing and email

The T-1 situation is solved—seems that for the past 5 millions years (according to Smirk, who has done something like 47 million of these things) The Monopolistic Phone Company has always provided the timing signal, so of course our DSU were set to use the timing signal provided by The Monopolistic Phone Company, but for some reason, in the recent past (read: a few weeks ago, possibly to spite us) no longer provide a timing signal for a point-to-point T-1.

The upshot: we now have to provide the timing signal. No big deal, once we figured out that The Monopolistic Phone Company no longer does that.

The company with the T-1 also has a wireless shot with us, and today they wrote in saying it was slow—only 1.1Mpbs to some random speed-testing site deep out into the Internet. I did a test more locally, from their side of the network to our side, using iperf and got a consistent 3.4Mbps—pretty much the maximum through the wireless connection.

Another customer with a wireless called in and he too, reported sub-optimal speeds, again, deep into the Internet. He wasn't in a position to run iperf but a few test pings throughout our network showed no problems. Once he started pinging outside our network to targets deep into the Internet, the speed drop was dramatic. I'm beginning to wonder if some of our routing peers are … problematic.

I'm still trying to resolve the email situation—we're now waiting for a response back from and Last time I checked, Lower Sheol was still hot.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site:, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
