Normal. Use a blow off tube.

LoL! Looks like the yeast is doing it's thing - probably a little better than you expected! I generally start with a blow-off tube, for the first couple days, to prevent that sort of problem, THEN switch to an air lock! I would think, for whatever that's worth, that as long as its still fermenting vigorously, you should be able to swap that airlock out with no worries...

Not to be an insult, but you have 3 other batches in the background of that picture, one of which seems like the Krausen went into the airlock, how do you not know this?

You will be fine, as long as the airlock had sanitisor or sanitized water in it. Like Shack01 said, if you are going to fill your carboys that full, but a blowoff on it and then an airlock when the Krausen dies back down.

This is the first time I've used Nottingham and the first time this has happened to me...as for the other three they got close to the top but never overfilled

Notty is some pretty volatile stuff. After almost having a fermenter explosion, I only use it occasionally on low abv batches.

New Yorkers think they’re so jaded that it’s impossible to shock them. They think they’ve seen and heard it all, and that may be mostly true. But I can tell you from experience that, at 2am in Midtown, pretty much every person on the street will stop and gawk when they see a guy holding hands with one midget, and another midget on his shoulders yelling out: “WHO RUN BARTERTOWN? I RUN BARTERTOWN!”

Me too. Each fermentation is different, so you never know when you are going to have one blow off. I have had low gravity brews go crazy and blow off and high gravity ones just chug along.

I often just leave to blow off tube in place for the whole time. It actually is just a big airlock.

If you want to avoid the entire mess that Nottingham produces (especially above 64-65 degrees) increase the headspace in the fermenter to allow for the krausen. I use a bucket that allows plenty of room and don't worry about oxygen because of the CO2 produced in the fermentation. 5 gallons in a 6 1/2 gallon bucket usually provides enough room for krausen.
