imgix is down again - 2hr+ outage and growing, only minimal details

What's the quickest image CDN ~plugin replacement? Something we can append w/h querystring and sign the URLs. We've been patient since April with all CEO promises (it's all going to change my friend, we're sorry and we'll be great again) but too many significant downtimes is not on, we don't believe they have the require devops skills no longer. We have more issues with imgix than anything else, patience exhausted, real explanations never anywhere to be seen.
