Shutting down Sapling 2023h2 and Oak 2023

This is a cross-post from

Howdy everyone,

This is to announce that we'll be shutting down our Sapling 2023h2 and Oak 2023 CT log shards this week. The Sapling shard is being decommissioned today, Feb. 27, while the Oak shard will be decommissioned effective Thursday, Feb. 29.

We're shutting down these aged-out shards to reduce operational load and reclaim resources. For a list of the logs we operate, check out the CT logs page on our website.

If you still need access to data from Oak 2023 after Feb. 29, you can try Google's read-only mirror, but please be aware that Google hasn't published any SLA or lifecycle guarantee about their mirrors:
