Yes, I'm aware the instance is down / having big issues since yesterday morning but I've not been able to fix that yet, being myself quite unavailable.
I'm unsure of what the cause might be, might be a DDoS like other instances had recently but this is still very unsure.
I'm working on it and will deploy new servers to handle the load tomorrow if needed.
Sorry for the inconvenience, this is a very frustrating situation as I cannot do enough to resolve it yet.
