A mental health website struggled to cope with demand after a promotional video voiced by the dukes and duchesses of Cambridge and Sussex aired on TV.
The Every Mind Matters website for a time was intermittently showing the message: “Something went wrong. Please refresh or try again later”
Public Health England said the crash may have been due to a surge in traffic but the website was now working.
