Http mail gstt nhs uk

It looks like you've provided a URL for the NHS (National Health Service) in the UK. Specifically, it appears to be the email address for the GSTT (Guy's and St Thomas' NHS Foundation Trust) mail server.

Here's a breakdown of the URL:

• http is the protocol used to access the website
• mail is the subdomain for the email server
• gstt is the domain name for Guy's and St Thomas' NHS Foundation Trust
• nhs is the top-level domain for the National Health Service in the UK
• uk is the country-code top-level domain for the United Kingdom

So, the full URL is http://mail.gstt.nhs.uk, which is likely the email server for Guy's and St Thomas' NHS Foundation Trust.
