Habib,<br><br>This is a community contributed table and used by multiple people. We mark a table as abusive if it seems to be hogging our resources, or consistently taking more than 30s to execute (this could also be due to a slow downstream source). This particular table seems to be getting marked as abusive more times than others. We also remove our blocks after a while, hence the sporadic working of the table.<br><br>I would advise that you wait for official tables from Yahoo! Finance if your application needs a stabler data source.<br><br>Sriram
