https://downdetector.com/status/github/ is a far more reliable source - it's just powered by user reports and often will show issues long before the status page ever receives an update.
Keep in mind that downdetector can be brigaded and/or show knock-on problems instead of root causes. e.g. A couple weeks ago there were fairly major spikes across a rather huge variety of services on there, but it turned out that it was actually Comcast that was having trouble, rather than any of the “down” services.
