Author here! I built this website because while PECO does have a very nice outage map (https://secure.peco.com/FaceBook/Pages/outagemap.aspx), I found that when I lost power and was sitting in the dark refreshing that status page that I really only cared about two things:

1) How many customers are affected?

2) And is that number going up or down?

That's it. I don't need a map, tons of assets, or tons of Javascript. So I decided to build this little website as a side project. All HTML and CSS is hand-coded. And with the exception of chart.js, all Javascript is hand coded, with the overall goal of trying to make the website drain cellphone batteries as little as possible.

It was all built out on Serverless, and is my first real project with Serverless! Static assets are stored in S3, served up via CloudFront, backend code is in Lambda, and data is stored in DynamoDB. Unless I get crushed with traffic, I expect this site will cost me less than a dollar per month to run. :-)
