CH Companies streaming API down?

I have been subscribing to the companies streaming API ( but since this afternoon / evening at around 5:40pm my logs are showing there is nothing being streamed. Is the API down?

Just to update - looks like someone turned the taps back on again around 7am this morning. Was this a maintenance outage (or a fault)?

Additionally, from logging the companies’ stream in the last month I have noticed that the stream disconnects when the cumulative payload reaches between 98MB and 100MB, is this by design (or a streaming protocol specification)?
