Uh… unsure of whether its better to let those 845M devices just expire.

Thanks to innovative thinking from our community and our wonderful partners @IdenTrustGov, we have a solution that allows us to maintain wide compatibility after our cross-signed intermediates expire.https://t.co/ATbrTmukAj

To many people, this blogpost will be complete gibberish. But it’s about something essential to using the web for 700m Android devices. The deep plumbing of the web, as essential as underground pipes in our cities, and as unseen. https://t.co/nN7qLB9UIj

It was wonderful to see the collaboration and problem solving that went into this. Great work all those involved! https://t.co/A2JPLz9ZX2

Lets Encrypt found a way to continue working on old androids. Hint: the droid thinks root certificates live forever.

Nice one, LE! https://t.co/fLeyAQJmlg

LetsEncrypt の DSTルート証明書の有効期限が延長された。
よかった、これで 古めのAndroidもしばらくは…https://t.co/TUVOrunPEQ

“IdenTrust has agreed to issue a 3-year cross-sign for our ISRG Root X1 from their DST Root CA X3.” 3年は延長してくれたってことか。 Let's Encrypt でも Android の古い端末で3年だけもちそう。 / “Extending Android Device Compatibility for Let's Encrypt Cert…” https://t.co/jEwLIFvRpV

Let's Encryptの旧Andoird問題取り急ぎ3年延命ですね！1月11日ショックは回避されたようです。 https://t.co/wfWi5goq6z

Let's Encryptの証明書切り替えは、古いAndroidデバイス向けになんかすごい頑張ったため、アナウンス済みの内容は実施しないことになったらしい。https://t.co/F5PMbOBets

古いAndroidでのLet’s encrypt延命、いいはなし。さらっと読む感じ、今まで使ってた”Identrust DST Root CA X3”(来年9月期限)でクロスルートにすることで解決。Androidがルート証明書の有効期限を見ない実装になので、期限切れした後もクロスルートが有効に成り立つ...https://t.co/5wqqtLoM1m

안드로이드 7.1.1 미만 기기에서 Let's Encrypt가 적용된 사이트 접속이 3년 더 가능해질 것으로 보입니다. IdenTrust가 ISRG Root X1를 DST Root CA X3으로 서명해주기로 한 겁니다. 따라서 2024년 초까지 걱정할 필요가 없습니다. 웹사이트 접속자는 물론 운영자도 말이죠.https://t.co/MsTphRdWui
