Are the other customers fed from the same utility pole as yours, or are they fed from a separate pole? If there's a separate pole, then I suggest it also be checked for the presence of power factor correction capacitors.

Utility mv capacitors switching than lv capacitors switching likely voltage transients
May also check neighbors same issue
As utility switch mv capacitors same time

I'll have to check with the neighbors and see if they are experiencing any issues
