API stopped working today, any known issues?

Hi, the API appears to have stopped working for my application today, 20/03/2019. Does anybody know of current issues, or anybody else having problems today?
Will try to generate a new API key and see if this helps, but if anyone knows anything please help.

I get MovedPermanently on this endpoint

https://api.companieshouse.gov.uk//company/{Company ID}/persons-with-significant-control

Live service is working correctly.
I have just tested curl -uMYKEY: https://api.companieshouse.gov.uk/company/04685039/persons-with-significant-control
and got:-
{“items_per_page”:25,“total_results”:1,“start_index”:0,“items”:[{“date_of_birth”:{“month”:2,“year”:1979},“kind”:“individual-person-with-significant-control”,“country_of_residence”:“Pakistan”,“natures_of_control”:[“right-to-appoint-and-remove-directors”],“links”:{“self”:"/company/04685039/persons-with-significant-control/individual/klpQJp8vTtM2HzrpQZ7_V8ti2gs"},“etag”:“731a4a01275e6abf9ea71f2211f5341a7e36e87e”,“nationality”:“Pakistani”,“name_elements”:{“surname”:“Khan”,“forename”:“Waris”,“title”:“Mr.”},“notified_on”:“2016-11-13”,“address”:{“premises”:“29 Harley Street”,“country”:“England”,“locality”:“London”,“postal_code”:“W1G 9QR”},“name”:“Mr. Waris Khan”}],“active_count”:1,“ceased_count”:0,“links”:{“self”:"/company/04685039/persons-with-significant-control"}}
back so no issues there either.

Thanks Mark
Just found out our IT guys did some rebooting which looks like they have broken something. As you suggest API is working and retested outside of the website environment via curl and all is okay.
