Getting "503 Rate Limit Exceeded" from Xtify Push API
===

I'm sending push notifications through Xtify 1.3 API and at top loads receiving in response an HTML message instead of JSON:

    <html><body><h1>503 Rate Limit Exceeded</h1></body></html>

Currently I'm sending the requests using 20-thread QUARTZ setup.

Could somebody help me figure out how to tune my API client to avoid looking as an attacker to the HTTP server or whatever part of the service is pushing me out?

Thanks, Alex
