Temporary suspensions of access to e-resources

To protect against excessive usage that risks breaching our e-resource licensing agreements and also the illegal harvesting of content from compromised accounts, the library imposes a 200MB limit on downloads in a single day.

Setting the daily download allowance at 200MB is an attempt to strike a reasonable balance between the different material file-sizes that staff and students may want to access across different subject areas. It’s a capacity that would allow the download of large numbers of journal article PDFs, but a far smaller number of high-resolution images or multimedia files.

If someone hits this limit, they will be blocked from accessing any more e-resources for 18 hours. If no further action is taken this block expires automatically.

To contact the library to expedite the lifting of a block, email libinfodirect@ntu.ac.uk with the subject line ‘eZproxy services suspended’.

The library will endeavour to unblock accounts in a timely manner before the standard 18 hour expiry but can’t guarantee it during particularly busy periods, or when the block stretches across the weekend or Bank Holidays.
