I used iron.io for years. Sad story there I think but I don’t know the details. Seemed like Great service for years then it kind of fell off, the service still worked thankfully. But no new features, and support would take days.
Thanks for using us! We ended up selling the service to private equity, hence the slowdown in features and support. Was an awesome and fun business to build but running a 24/7/365 service just as all the cloud providers were adding similar products was a slog.
