Don't Pick AWS us-east (if you can)

After large AWS incidents, they post a post-mortem on this list.

As of today, there are 16 outages that AWS considers as significant.

Of these 16 outages, 8 were from the us-east regions. Four of those eight were in us-east-1.

If you were starting today and can afford it, I’d recommend using the us-west regions.

EC2 instances and everything in costs more in general in us-west. However, in the future, you might never need to engineer your workloads for multiple regions.
