Error 500 : Backend Error

[GoogleCodeExporter]

When I run a simple Query, sometimes works, sometimes I get this message:

/* Error in runSyncQuery:'{\n "error": {\n  "errors": [\n   {\n    "domain": 
"global",\n    "reason": "backendError",\n    "message": "Backend Error"\n   
}\n  ],\n  "code": 500,\n  "message": "Backend Error"\n }\n}\n'
None */

My system is down. Can anyone help me?

My project id : poc-big-query-815

Python scripts are executing the queries

This looks like a problem with the API infrastructure that sits in front of 
BigQuery, rather than with BigQuery's servers. Most likely, your query never 
even got to BigQuery.

Generally speaking, the solution to these problems is to retry your query 
requests. If you want to avoid creating duplicate query jobs, you can create 
your queries by calling jobs.insert with a client-generated job ID, and retry 
on the same job ID when necessary. Our API guarantees that you can only create 
a given job ID once, so as soon as you see a response that says that your 
jobs.insert succeeded (or that it failed because the job ID was already known), 
then you can stop retrying.

I'm going to close this bug to keep things tidy, but don't hesitate to reopen 
if you have further questions or problems.
