from 10h00 26 april, in my project on bigquery my datasets and tables has been lost. Moreover bigquery doesn't execute my sql queries that I've been regularly executing until yesterday. I didnt change anything from yesterday. The only message error I get is An internal error occurred and the request could not be completed. This is usually caused by a transient issue. Retrying the job with back-off as described in the BigQuery SLA should solve the problem: https://cloud.google.com/bigquery/sla. If the error continues to occur please contact support at https://cloud.google.com/support.
