How to get information that server doesn't provide tile for this zoom and area?

I have such problem:

For certain areas of maps there are no accesible tiles for high zoom levels.

In such situation in mapbox expected map tiles are replaced by information that server returned error 404.

I would like to react automatically and change zoom to the available level.

How can program know that such situation appeared? I can't for example catch an webexception because it is earlier served by BruTile.

Thanks in advance

If BruTile is already catching the exception, it is probably necessary to have BruTile changed. I'll check with Paul.
