If it's a Heroku error then they obviously have staff monitoring servers 24x7. Usually I get very quick responses from Heroku Support at all times during the day, regardless of the type of inquiry - either basic questions or platform problems. Obviously they would filter incoming requests. If you pay for support you get a quick er response. If you have a question without paying you might have to wait a bit longer during off-peak (US) hours. But if it's a platform error I'm pretty sure they would filter that out and respond quickly.

And what are you comparing to here? Are you getting instant 24x7 free support from any other vendors? It's quite normal to pay for support in this industry.
