Randomly getting 'Internal Server Error'

[cspeer]

Hi there,

my application needs read access only, thus I'm only passing a consumer_key in the query string. Also the only endpoint I'm using is photos/search:

GET https://api.500px.com/v1/photos/search ?consumer_key=******** &geo=50.937531,6.9602786,10km &only=City and Architecture,Landscapes,Street,Travel,Urban Exploration &image_size=2 &sort=times_viewed &rpp=1

Randomly this endpoint returns nothing but

{
error: "Internal Server Error",
status: 500
}

Any ideas?

Thanks Chris
