My site may suddenly get a ton of traffic

a project I worked on looks like it might be featured in Wired. I know DH throws out the day of highest bandwidth, but I’m curious if you need any sort of warning so I’m not taking down other people’s sites on the same machine. I plan to throttle the bandwidth (will the throttle kick in before the day of highest bandwidth is thrown out?)

what would DH advise in this case?
