Taxiing to Runway 8 at SJU; we were cleared to taxi and hold short at S1. I noticed the Captain wasn't going to make the turn at S1; so I prompted him; but it was too late and stopped just past the intersection. Tower called us and said that S intersection was closed; so there was no way for us to turn around and return to S1. Tower called a follow me ops vehicle and instructed us to follow him through S intersection; onto the runway and then taxi off at S2. We complied and returned for takeoff from S1. We missed complying with the taxi instructions; but there were no markings of the closed intersection; and the ATIS was unclear; stating only 'S intersection closed'; which seemed ambiguous since it didn't mention S at Runway 8 closed.
Air Carrier pilot reported unclear ATIS information and a lack of markings resulted in a taxiway incursion at SJU.
