Amazon’s virtual assistant Alexa has crashed across Europe this morning — leaving some frustrated users unable to turn off their alarms.

According to Down Detector, a website that monitors such issues, 已经超过了 8,000 reports of problems with the smart devices.

Issues first began to surface at around 07:00 GMT today.

When issuing voice commands to Alexa devices, users are either being met with silence or have received messages saying ‘something went wrong’.

Others are seeing a ring of red lights and a message to try again later.

It appears the issue is affecting Amazon’s range of Echo speakers as well as the retail giant’s Fire TV Stick and Amazon Alexa app for smartphones.

People across the UK have been complaining about the problems, while there are also reports that customers in Germany and Italy have been affected.

Angry Alexa users have taken to social media to complain about their devices.

Tony Sibley tweeted: ‘Trying to find my light switches this morning. #AlexaDown’.

另一个使用者, Chloe Hardman, 写: ‘Alexa is down and won’t turn our alarm off.’

Some say their Echo Dot is not working properly even after a hard reset.

The virtual assistant is built into millions of devices available in the UK, including smart speakers and home hubs, which can be used to control appliances around the home.

Amazon has been contacted for comment on the issue. The tech firm has so far not confirmed the cause of the problem.

Jake Moore, global cyber security adviser at ESET, 说过: ‘Although it is difficult to predict whether or not this is a cyber attack on Amazon’s servers, it does pose the question of whether or not we are putting too much emphasis on smart technology in our homes.

‘Cyber attacks are still possible despite the increasingly sophisticated anti-malware technology that exists, and therefore we must never become complacent against the possibility of such a hack which can dramatically effect large numbers of people.

‘Once we put all our eggs into one technological basket, there becomes one simple point of failure that can have a huge impact in a smart home and therefore our daily lives.

‘Using smart devices to control lights, heating and other areas of a home is extremely tempting but it is advised to always know if the backup “old fashioned” switches are still applicable.’
