Net::HTTP request connection too slow?

Question

I've the following code that I've extract from ovh-rest gem:

method = :get
@api_url = "https://api.ovh.com/1.0"
@api_key, @api_secret, @consumer_key = "123456789", "abcdef", "ghijkl"
endpoint = "/ip/123.456.678/"
url = @api_url + endpoint
uri = URI.parse(url)
body = nil
ts = Time.now.to_i.to_s
sig = "$1$" + Digest::SHA1.hexdigest("#{@api_secret}+#{@consumer_key}+#{method.upcase}+#{url}+#{body}+#{ts}")
request_uri = uri.path
request_uri += '?' + uri.query if uri.query
request = Net::HTTP.const_get(method.capitalize).new(request_uri)
request["X-Ovh-Application"] = @api_key
request["X-Ovh-Consumer"] = @consumer_key
request["X-Ovh-Timestamp"] = ts
request["X-Ovh-Signature"] = sig
request["Content-type"] = "application/json"
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
response = http.request(request)
JSON.parse(response.body)

If I do everything step by step I've the following error:

{
  "errorCode": "QUERY_TIME_OUT",
  "httpCode": "400 Bad Request",
  "message": "Query out of time"
} 

But if I wait some seconds (variable duration) before doing response = http.request(request), I've a successful request:

{
  "organisationId": "nil",
  "country": "myCountry",
  "routedTo": {
    "serviceName": "somename"
  },
  "ip": "123.456.678/32",
  "canBeTerminated": true,
  "type": "failover",
  "description": "nil"
}

I don't know if the problem comes from my server (ruby process to high for quick response) or if it's coming from somewhere else around..

Important note :

This code was working like a charm but some days ago.. Stop working.

This was solved by a date resynchro. Since all servers' hours are the same, it works like a charm.
