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.

”Red Alert!” “Where? I don't see any lerts around here!”

Yesterday felt like Friday, mainly because The Weekly Meeting™ was canceled at the last minute, thus I didn't have to leave The Home Office.

But it was still a weekday today when I got a call rather early from Smirk. “Sean!” he yelled through the phone into my ear, “not only do we have a customer down, but we have network traces that show it's our equipment that's down!” Behind him I could hear the Klaxons™ in the background.

I mumbled something about calling him back, wandered over to The Home Office, and started a Level Five Diagnostic Program poking into the routers.

I've never seen that happen to a Cisco router before.

I called Smirk back. “Smirk, you better get G [our Cisco consultant —Editor] on the phone to diagnose this issue. I'm out of my league.”

And thus began a few hours of scrambling to get a replacement router for the customer, and by the time I got onsite with a temporary replacement, I was told it was too late to do the change (the current router was still limping along—these crashes were happening about every half hour) and that they were planning on taking down the network at 11:00 tomorrow, so I could do the replacement then.

Wonderful!

Worse, is that this isn't the first time this router has had problems. A few weeks ago we appeared to have a similar issue and ended up replacing one of the interfaces (the errors weren't nearly as scary then). I remarked at the time that I had never seen a Cisco router go bad (I've been working with Smirk at The Company for five years now and this is a first—and even when I worked at a webhosting company in the late 90s, never saw a bad Cisco router, nor did I come across one when working at two ISPs (one in the mid 90s, and one around the turn of the century). Smirk also informed the customer, multiple times since then, that they need a redundant router, but the request never made it past a certain level of management.

Sigh.

Obligatory Links

Obligatory Miscellaneous

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: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

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.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
