If you try to open an online resource and get the error message File missing: docs/suspend.htm, it means you have exceeded the maximum amount of data allowed to be downloaded through our proxy server.
We have a usage limit to prevent unethical use of resources, such as downloading entire runs of journals. Publishers and database providers usually prohibit that sort of excessive usage, and sometimes suspend a library's access to their products if they suspect someone is abusing their privileges. Although perfectly normal usage can sometimes trigger the usage limit, it exists to protect everyone's access to library resources.
If this happens, you could try waiting 30 minutes before you try again. However, the suspension time may prevent you from connecting for at least 120 minutes.
