Narrative:

On A523 approximately 200 NM prior to flann, we called for clearance to deviate 60 mi right of course for WX. We then changed the request to 80 mi right. We got the clearance as requested. We were at FL250 and couldn't get over or find a way around the WX. We needed significantly more deviation and tried to get clearance both on HF and on VHF through a relay with another company flight. We exceeded the 80 mi deviation clearance by a significant amount before being able to contact ATC. Finally got radar contact and received clearance to climb. Diverted to bos due insufficient fuel. Supplemental information from acn 481985: en route to jfk, communicating with new york commercial radio. We exceeded the 80 NM clearance. Shortly afterwards, we were in radar contact with ZNY and received clearance to climb to a higher altitude, which enabled us to clear the WX. Due to unforecast WX, we diverted to boston where we refueled and finished the flight safely.
