No as in proof reading or no as in the headline is correct?
I know that many people can confuse wreck and wreak but wreak means "to cause damage".
In this instance I'm damned sure that the ISP cut off will "wreak havoc" amongst a homeowner's smart devices, leaving them on a "wreck".
Obviously it was just a crap joke on my part...

(Does anybody bother proof reading any more? And so misspell the reply....

And yes, it's wreak not wreck!
