IP blocked due to re-requesting files too often

Your IP address has been blocked from accessing our site for 2 hours due to abuse.

The specific type of abuse we observed is: re-requesting the same resource too frequently. Specifically, we received at least 150 requests for the same resource (URI) from your IP address within a ten-minute time interval.

If you are using an application that makes HTTP requests to other sites, please configure it to use an outgoing HTTP cache instead of re-requesting the same files over and over again.

If you are a corporate user, please check with your network administrators who should be able to determine the source of the excessive traffic coming from your network. (please refer them to this page)

Once the issue has been resolved, you will be removed from our blocklist automatically within 24 hours; there is no need to contact us in order to be delisted.
