"Ozone bubble" avoidance

Hello Fellow PPruners !

I have flown few days ago over the East coast of the US and some airliners were asking ATC to "descend to avoid a bubble/layer of Ozone" in the mid-thirties (thousands of feet).
They also said that they got the heads'up from their Operations.
We flew ourselves ABOVE (at FL430) since I (vaguely) understood that this layer was limited in altitude (let's say FL 330 to 360) and it was not exactly at our position then.

It is the first time I hear something like this....
Is it frequent ? How do Operations know about it ? Shall we pay more attention to this phenomenon ? are the pax/crew at risk or also the engines ?

Thanks a lot for your valuable inputs as always !

MERRY CHRISTMAS !!

Leo
