At the same time, we have monitoring for any sudden changes to tests that our customers are running.You are probably safe. We have the standard monitoring to make sure that systems are performing properly, data is flowing through our infrastructure, etc. As a monitoring and observability company, we have a lot of monitoring built into our systems, as well. This is due to a recently expired security certificate many websites use and your computer or some. Reports of this issue are mainly when using Safari or Chrome on Mac OS.

These types of incidents are pretty rare.When you request an HTTPS connection to a webpage, the website will initially send its SSL certificate to your browser.Your Connection Is Not Secure How To Solve ItDo You Trust Let’s Encrypt?Before we get into the weeds, I just want to say that I, personally, trust Let’s Encrypt. We also share our incident review of the event, so that the learnings will help others. While this is true for some, it does not solve the problem in general!Below we explain why, and how to solve it on the server-side so that all of your clients can access your web service without issues. Furthermore, as we work with many vendors, we’ve received updates from some which indicate that solving this problem is as easy as downloading the latest OS updates.That’s exactly what happened on the evening of September 29 and again on the morning of September 30, 2021. One of them is that Google has been gradually forcing sites to use HTTPS by making HTTP-based sites “not secure.” Still, no matter the cause, in that amount of time Let’s Encrypt has gone from issuing certificates for about 50M websites to over 230M!At the same time, it doesn’t matter that I trust Let’s Encrypt if computers don’t. Whether you’re checking your bank balance, buying a new pair of socks from an e-tailer, or talking to your friends, you do so with the assumption that this transaction is secure.In the last ~8 years (2013-2020), the percent of web pages using HTTPS has gone from 25% to over 84%! There are several reasons for this incredible growth. It’s the basis for secure communications. Encryption is extremely important on the Internet. At this moment, the MacOS laptop I’m writing this on has 161 “System Root certificates” installed. If you have a computer that can connect to an HTTPS website, you have such a certificate store. These are issued by major companies under a lot of scrutiny and are installed in the Certificate Stores of computers worldwide by the company that developed and maintains the OS. Root certificates: There are a handful of Root certificates. Bmc track it clientIntermediate certificates: When you go to the HTTPS website, the server hosting the website sends the certificate during the SSL handshake with the client (browser/HTTP client). In this way, there is a chain of trust from the website’s certificate all the way to the root certificate. Some have their own Root certificate and others have a Certificate Authority certificate, which was signed by one of the Root certificates or by another Certificate Authority. There are many providers to choose from. Therefore, they purchase a certificate from a provider. Edgar cayce past life readingIf it makes it all the way to the root and finds it in its “store,” the chain is validated, and the connection is allowed to proceed. Validation process: Your browser “walks” the chain of trust, from the server certificate up to the root. These intermediate certificates are what it thinks you might need to connect the chain of trust from the server certificate to one of the root certificates you installed on your computer. For example:It turns out that the certificate needs to be updated in your computer – usually through a Windows or MacOS update – before it’ll work. Since this is an intermediate certificate, this means that Let’s Encrypt used this certificate to sign other certificates for their customers. Here’s the certificate information for this intermediate certificate:The most important piece of information here is the expiration date. The details are a little confusing, but bear with me.Originally, the DST Root CA X3 was used to sign all Let’s Encrypt certificates (including the R3 intermediate certificate above). September 30th, 10AM EST: DST Root CA X3 Certificate Expiry And The ConsequencesAt 10AM on September 30, the DST Root CA X3 certificate expired. Now you can go to any of those millions of sites with Let’s Encrypt certificates, right? Well, sort of.until 10AM Eastern the following morning. Even worse, a lot of embedded devices rarely if ever update their certificates! Someone here at Catchpoint mentioned that his kids couldn’t watch their favorite streaming show from his SmartTV because of this issue!So, OK – let’s say you got the latest R3 intermediate certificate installed in your whole fleet of devices. ![]() ![]() Because of this large fleet, we saw and solved almost every flavor of the issues described above.However, the customers accessing your website probably don’t have a 24/7 Operations team. These agents have different configurations of hardware, software, firmware, etc. In Conclusion.Here at Catchpoint, we have a huge footprint of test agents in every corner of the world. Others need both to be valid but they’re not, because the DST certificate is expired!Now, the server sends the self-signed ISRG root certificate, which an updated client will be able to validate without needing the expired DST root certificate. They then find that the ISRG certificate is valid and they’re satisfied.
