Google seems to be playing games with Antrigravity users

I don’t understand. Yesterday everything went well, with the occasional 503 error, and I barely used any quota. But today it’s the same again: constant errors, no work, and I’ll probably waste my quota trying over and over. This happened to me again on Tuesday (everything was fine, but on Wednesday nothing worked). It’s a disgrace. I don’t know what Google is playing at. Are they balancing the servers so they work for some one day and for others the next, just to keep people from getting so frustrated? That’s what we’re using Ultra Business accounts for, after all. And as always, there’s no communication or transparent explanation of how the service is being provided.
