Umm.. let's think more carefully here. A major *MAJOR* player is changing a config *during prime time*? Hell, we're not that big, and we get 3AM-7AM local. ANything else is emergency-only. So we'll assume that the *real* timeline was: 5PM something *else* melts 6:30PM change a config to stop THAT emergency 6:45PM notice you've scrogged it up <next 19 hours> try to decide which is worse, the DNS being screwed but your *local* operations are back online using local private secondaries, or DNS being OK but whatever was loose trashing the corporate backbone? Meanwhile, your OTHER set of network monkeys is busy fighting whatever fire melted stuff to start with... <META MODE="so totally hypothetical we won't even GO there..."> They'd not be the first organization this week that had to make an emergency router config change because Ramen multicasting was melting their routers, or the first to not get it right on the first try. They'd merely be the ones thinking hardest how to put the right spin on it... </META>` I have *NO* evidence that Ramen was the actual cause other than it's this week's problem. However, I'm pretty sure that *whatever* happened, the poor router tech was *already* having a Very Bad Day before he ever GOT to the part where he changed the config.....
