MPs have raised concerns that “key parts” of UK IT infrastructure are hosted abroad after disruption to Amazon Web Services led to outages across a wide range of internet services including HMRC, Halifax and Lloyds.
Downdetector, a website which tracks complaints about online services, showed a spike in reports on Monday, with thousands reporting outages at Amazon Web Services (AWS), HM Revenue & Customs (HMRC) as well as at Snapchat, Starbucks, Slack and Ring.
