Debian 11 aka Bullseye was released some days ago, then Debian backports suites from deb.kaliko.me will be updated.

• First I will remove oldstable stretch backports
• Then I will start a new suite bullseye-backports and update stable-backports to point to bullseye-backports.

If you had set stable-backports suite in your sources, pay attention as it will then point to bullseye backports instead of buster.

In order to keep following oldstable aka buster (debian 10), please update from stable-backports to buster-backports in your source list.
