Why is Apex not available?

Excuse me, but I was wondering if you could shed some light on the matter of Apex's unavailability. I've been trying to access their services, but to no avail. Could there be a technical issue or perhaps a scheduled maintenance period that I'm unaware of? I'm curious to understand the reasons behind their inaccessibility and if there's a timeframe for when they might be back up and running. Thank you for your time and assistance in this matter.
