Pingdom check for homepage failing

Pingdom monitors externally (from ~10 locations in Europe and America) that it can connect to https://www.gov.uk. If this fails it could indicate that DNS for www.gov.uk is not working, our CDN has failed or GOV.UK and all the static mirrors are inaccessible, which would qualify as a major incident.

If you can confirm that GOV.UK is globally inaccessible, then this is probably cause to first alert other people who may be able to help, then start troubleshooting to see if you can narrow down the failure.
