Let’s Encrypt’s DST Root CA X3 CA security certificate will expire, which tends to connect with some old devices.
September 30, 2021.- This Thursday, September 30, an important event related to the world of technology will take place: an internet blackout that will involve several devices that will not be able to connect to the network .
Said blackout refers to an authentication certificate expiration that helps to validate the network connection –of a server– of some devices.
In this case, it will be given with the Let’s Encrypt DST Root CA X3 CA security certificate , which usually connects with some old devices.
The Let’s Encrypt certificate is mainly found in old mobile devices, whether they are cell phones, video game consoles, tablets, televisions.
Such out-of-date devices will become obsolete to connect to the internet as of September 30, unless the firmware (the program that controls the electronic circuits of a device) is updated.
Get advice from Boulder developer @phasmantistes on how you should prepare for the upcoming root expiration (and if it will affect you at all) in a new video from the Let’s Encrypt team: https://t.co/IkEMxd3wOJ
