SSL handshake performance improvements with NVMe-based storage

We’ve completed a migration of our certificate storage from SSD to NVMe-based storage to improve SSL handshake times for domains that aren't cached at a specific edge node location. Since uncached domains need to retrieve certificates from storage, switching to NVMe-based storage enables faster certificate retrieval. This results in better performance, particularly in the 99th percentile of requests where certificates aren’t already cached.

With this migration finished, we continue our mission to provide the fastest redirecting platform out there.

We’ve also added a hot-spare option for our certificate storage. In case of maintenance or outages on our primary storage, we can now seamlessly switch to this hot-spare, allowing faster recovery and increased platform reliability.
