If you consider to use Google Cloud Platform it's important to know that their SLA is practically useless. It only includes requests with HTTP Status code 500. If the system is not responding at all it's not covered by the SLA. See their definition of "Error rate": <a href="https://cloud.google.com/storage/sla" rel="nofollow">https://cloud.google.com/storage/sla</a><p>This is not just a theoretical issue. In the past week we've been doing a bit more than 5 request/sec to Google Cloud Storage and according to NewRelic the average response time was 8 seconds! I.e. the service has been down and not been responding at all for large periods of time. I've been in contact with their support team and they've refused to reimburse us anything.
