What's affected by internet outage - all we know so far

Dozens of websites, banks and apps are being affected by a major internet outage. 

The problem, which started on Monday morning, appears to be related to an issue at Amazon Web Services (AWS).

As of 9.20am (UK time), there were more than 2,000 reports of the Amazon Web Services outage in the US alone, according to Downdetector, which monitors issues and outages in real-time.

Just before midday, AWS said it had fixed the underlying problem, but said it had a backlog the system will need to deal with.

Here's what we know so far.

What has been affected?

What has AWS said?

AWS confirmed it was suffering from "increased error rates and latencies" for multiple services.

The company said its engineers were "immediately engaged" as soon as they spotted the issue.

It said the error was caused by a problem with companies connecting to data services at AWS's data centres in northern Virginia.

There are believed to still be some problems with a server service called EC2, or Amazon Elastic Compute Cloud, which the company is trying to resolve.

It recommended anyone still seeing problems with DynamoDB to "flush their DNS caches", which will refresh the connection.

What to do if you are affected

Sky News' science and technology reporter Mickey Carroll says those affected by the outage are partly at the mercy of AWS to get their services back up and running.

If you are still experiencing delays, Hayley Andrews Smith, an automations specialist working at Myriad, advised people on LinkedIn to check their business's automated processes as "anything hosted on AWS might be affected".

She also suggested pausing critical workflows until the systems are back up.

Carroll says people should also keep their guard up for scammers.

Has something like this happened before?

In July last year, American cybersecurity company CrowdStrike accidentally brought parts of the world to a standstill when a faulty software update caused a global IT outage.

It took just 78 minutes for the company to identify the problem and start rolling out a fix, but the impact disrupted internet services, affecting 8.5 million Microsoft Windows devices.

In the UK, the outage also left GPs unable to access systems that manage appointments or allow them to view patient records or even send prescriptions to pharmacies.

Flights were cancelled or delayed and passengers were left stranded as airline systems were knocked offline or staff were forced to handwrite boarding passes and luggage tags.

The company has now been sued by its own shareholders as well as Delta Airlines after it cancelled thousands of flights.
