Website security upgrade

This week we've strengthened the security of our websites with an additional application firewall. It works in the background to block automated attacks and malicious requests before they reach your site, helping keep your content and data safe.

You shouldn't notice any difference in everyday use. However, with any new security layer, occasionally a legitimate request can be blocked by mistake. If you see a "403 Forbidden" message that you weren't expecting, please let us know so we can fine-tune the filters.

To help us track it down, please include:

• The page address (URL) where it happened
• What you were doing at the time (for example, saving a form, uploading a file, or pasting text into a field)
• The date and approximate time
• If you can, a screenshot of the message is also very helpful.

Please send reports to me by email. Thank you for your patience and help while we get the settings just right.
