Backblaze 發了「Announcing Support for IPv6」這篇公告，宣佈支援 IPv6。
不過跟 AWS 採用 opt-in 的作法不太一樣，他們是直接全上 IPv6 了：
No action needed on your part: Unlike some of the traditional cloud providers, we chose to use the same endpoint URL and let the client choose whether or not to use IPv6. This allows for any systems already IPv6 enabled to benefit immediately. In fact, if your systems are IPv6 enabled and you are a B2 customer using the S3 compatible API, you might already be connecting to us over IPv6 now.
看起來沒有切換時間，是 rolling update：
While our IPv6 deployment isn’t completely done yet (we’re phasing the roll out through our environment), we thought we’d share some of the decisions we made that affect performance and functionality.
這種作法對於企業客戶來說看起來不是什麼好事，如果機器的 IPv6 stack 是爛的，而且沒有 Happy Eyeballs 或是類似可以偵測哪邊是通的演算法的話，就直接爛掉了。
往 IPv6 推是蠻重要的沒錯，但這麼簡單粗暴好嗎 XD
