The UK Government website - gov.uk - was also not working, giving the error message "Error 503 Service Unavailable", though most websites appeared to be back online by 11.45am. Visitors to the Guardian and several other sites received an error message stating "connection failure" or "Fastly error: unknown domain". Fastly, one of the world’s major CDNs, has reported a major outage across its global network, which is believed to have caused the outage. One wrote: "@GOVUK your website is down and I need to complete a passenger locator form ASAP." “Given the nature of this kind of technology, it’s probably not a software issue,” said Adam Leon Smith, from BCS, The Chartered Institute for IT.
