No answer from certain queries for isochrones

[Dis Tract]

When I query for isochrones at lat lon  40.87668, -97.09879   context here:

http://www.openstreetmap.org/search?query=40.87668%2C-97.09879#map=17/40.87668/-97.09879

which is in the middle of a building, not very far from the nearest road, I get no answer from the web and the API version.

Is this a known issue?

When I moved the lat lon to the nearest road it works fine.

I can wrap my queries in a shim that finds the nearest road segment via OSM and retries but it seems that would be better handled for reasonable cases server side.

Other queries that give the same null answer:

37.04076, -76.37905
44.82852, -93.16191
42.01283, -87.71914
