Us-east-1 is far far from least reliable. It’s one of the more reliable ones. Smaller regions tend to have more reliability issues affecting the entire AZ.

This analysis is skewed due to the major incident in 2025. What was the data for 2024 and over the last, say, 5 years? So the proclamation of least reliable of us-east-1 is based on 1 year of data, and it’s probably fair to say that at least last 3 years if not 5 are a better predictor of reliability.

us-east-1 also hosts some special things, so it will have more services to lose.
