Was flying in Maine, seems the controller's minimum altitudes they assign have all been raised lately by exactly 500 feet. In fact, one of them said pretty well that. Wondering, how big an area this change may apply to, or is it eastern "mountainous" areas?

Touchdown! Greaser!
Was there a tower or towers built in the sector? Those can raise assigned altitudes of that magnitude.

Final Approach
There's been some rethinking lately about Obstacle Clearance Reductions, sounds like action has been taken. AVN had been able to approve reductions to Required Obstacle Clearance in mountainous areas when required to achieve compatibility with terminal routes or to permit vectoring to an instrument approach. In areas served by ASR the reduction could have been as much as 1000 feet. In areas served by ARSR the reduction could have also been as much as 1000 feet for man-made obstacles, for terrain it could be up to 500 feet in the eastern US and 300 feet in the western US.

Thanks Mr. McNicoll, as usual you seem to have been right on. Talked to a BOS supervisor, got a story along the lines of:
"Changed criteria for terrain, due to results of a few incidents, going on for awhile now, 1000 or 2000 ft obstacle clearance was standard, but with some deductions was previously allowed. Now there are more restrictions. Expect it all through the country, some airways mea's going up....there were reductions for non preciptous terrain, the FAA has tightened the criteria..."
Guess that's it.
