Random Geek Amusement

Here's some random geeky amusement for the day...

I was working on deneb (my server at home, 15 miles away), when I noticed that for some odd reason the latency went up to something like 2 seconds (for you non-geeks, latency is the time it takes for a computer to respond to something that's sent over the network). So I did a traceroute to figure out what was going on...

I guess someone over at Sprint rebooted a router, because packets were going from here (on campus), to LA, to Washington, to London, to Frankfurt and then to Denmark before finally coming back over here (looks like through New York and Georgia).

So packets that were destined for a computer 15 miles away ended up having to travel around the entire world. I find that highly amusing.

Normally, the traceroute looks like this:

...and that leads me to believe that it was Sprint's fault. Everything's happy now, though, so I'm not complaining. I'm just highly amused.

    Well, I'm off to Dreamwidth. I hope to see you all there! Nice knowing you, LJ. It's been grand. — Des

    So I'm thinking of moving away from LJ. Every time I glance at my ad blocker, there are an uncomfortably-large number of advertising and tracking…
