We had the usual database outage, this time exercising the new replica. We stopped the project and confirmed all the table counts matched. That gave me warm fuzzies. We then simultaneously compressed the tables on the master while backing up to disk from the replica. Doing these things in parallel would have normally shortened the length of the outage...

But Jeff and I took this opportunity to clean up the closet. It's a mess in there and we're trying to get rid of unused junk to make way for new stuff. Today we kept it simple: remove the switch/firewall used for our (now defunct) Cogent link, and move the current set of routers/switches into one general location on the rack so wires won't be all over the place. The latter required power cycling the router which is our end of the tunnel from our current ISP (Hurricane Electric). Upon reboot, packet traffic wasn't passing through at all.

Well, that's not entirely true - packets were going through (in both directions) but more or less stopping dead after that. It was a total mystery. A five minute reboot became a four hour detective case. Jeff and I pored through IOS manuals and configurations, testing this, rebooting that, and googling our way into and out of several red herrings.

Long story short, after a few hours we noticed traffic was back to normal and had been for some time. Hunh? Apparently one of our tests tickled something into working, so we rebooted the router again bringing us back into the mystery state. We finally found the magic bullet: pinging from inside the router to the next physical hop down on campus opened the floodgates. Why? That's still a mystery, but at least we know a fix when we get jammed again. Probably has something to do with router configuration somewhere expected an established connection before passing packets along.

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind...
