If you read the wiki of the Carrington event, telegraph operators were getting electrocuted and the pylons were throwing sparks because of the EM induction. I could be wrong, but this doesn't sound like an event the grid or consumer electronics are designed to handle.

Some people today estimate that you really only need to take down around a dozen key power stations to essentially take down the whole grid in the lower 48. If the Carrington event was indeed worldwide, we wouldn't be able to get back to where we were for a while. We're talking little or no electricity, little or no radio, etc.

Again, the question really comes down to "What are the odds?" The CE seems to be very, very unlikely. If there were a handful of historical accounts of aurora in equatorial regions worldwide I think we'd be much more proactive about it.
