Problem with service drop
Regardless of who's responsible money wise, you should call your utility company's repair line now.  If it's before the meter, they need to be involved in disconnecting the service either way.

Generally they will send someone out to inspect it and let you know if it needs repairs.  They'll also tell you whether you need to pay for the repairs or not...but either way they need to look at it right away, so it makes no difference in what you need to do.

Different hydro companies have different rules, but generally the demarcation point (where it goes from being their problem to your problem) is either at the top of the service stack, or at the terminals on the house's side of the meter.  Everything before there is their job to fix.
