Suggest Nearby throws a 503

[hkrishna]

Odd behavior around /suggest/nearby in prod (pelias.mapzen.com) service.

The following URLs dont work:
https://pelias.mapzen.com/suggest/nearby?input=east&lat=41.9184&lon=-87.6493&size=10
https://pelias.mapzen.com/suggest/nearby?input=east&lat=41.9184&lon=-87.6493&size=10&zoom=3

But this works:
https://pelias.mapzen.com/suggest/nearby?input=east&lat=41.9184&lon=-87.6493&size=10&zoom=4

which leads me to believe that there is something weird going on with the suggester trying to use precision level 1. If you do not pass in the optional zoom parameter, by default the suggester query constructor assumes its zoom 1-3 and falls back to precision 1 (which is the lowest precision level). Here's the relevant line of code 11:35
https://github.com/pelias/api/blob/master/query/suggest.js#L27

However, we need to do some more investigation around the production instance and see if its an Ops related bug. The reason I say that is because it seems to work locally and in dev instances. @heffergm may be able to provide more insight if its an ops issue?

@sevko could you dig a little deeper through the code and report if its a bug in our queries/sanitizers etc?

Thank you Blane Bell for bringing this to our attention. We are on it :)
