On 17 October, there was a multi-AZ network failure at us-east-1. It only lasted 3m35s, but it was enough that our customers were calling about our site being down.
I took several years away from the front-end to focus on Backend and DevOps, only recently re-upping my front-end-fu. Since I knew CSS 2.0, I found Bootstrap quite easy to pick up and be productive with in about a day, not previously knowing CSS griding. And I found myself saying over again, holy shit where was this back in "my day"!
They also make a ridiculously amazing Solar charger array, which when I took across a border to Israel, had the inspectors in serious awe and wishing they could get one as inexpensively as we can in the States.
