(un)Trusted Certificate Services - a swift transition
At SURF, we learned about the contractual developments between GÉANT and the TCS4 supplier in October 2024. After assessing the situation and concluding that the chance of the negotiations going south was high, we concluded it was time to prepare our constituents for the worst-case: service interruption. In this lightning talk we explain what we did, how we prepared our constituents, why we chose to do this so early in the process and how we onboarded more than 60% of our userbase within the first two weeks of having HARICA as the new supplier.
