What if your computer, smartphone or game console had no internet connection? This is what is likely to happen on September 30 to several million users.

In question: the expiry of a digital security certificate, the IdentTrust DST Root CA X3. It was computer security researcher Scott Helme who warned of the effects of this expiration in an article published on his blog and relayed by Phonandroid.

So this could affect many devices, old ones that still rely on IdentTrust DST Root CA X3. It is in particular the devices released before 2017 that are concerned. Sometimes a simple update can fix the problem.

How to avoid failure?

According to Scott Helme, a third of Android phones could be affected by the September 30 outage. They need to install version 2.3.6 Gingerbread or an earlier version to be able to maintain the internet connection. For Apple devices, to avoid this issue, users of macOS 10.12.0, iOS 9 or earlier are advised to update the firmware. Same for PlayStation 4.

To anticipate this possible cut, you must update your device. As far as web browsing is concerned, it would suffice to use certain browsers such as Firefox which use their own security certificates to overcome this connection problem.
