Some info gathered!

Anyways no, mggo will NOT shut down. It is NOT on the list of the ones atleast been revealed. The maintenance earlier was most likely a cloudfare issue not a possible take down issues. You may be however be laggy due to your location or honestly your use of VPN (ik its for safe purposes) but it does play a role.

Also this was in their guides:
Troubleshooting Mangago Issues
- Clear your browser cache.
- Try different browsers or devices.
- Check your internet connection.
- Look out for maintenance announcements. (only actual active official one they have is in FB, i think deactivated now as we speak since their last announcement was in 2022 when forums reopened)

Mangago... Is from asia. Yes I FOUND OUT WHERE THEY MAY EXACTLY OPERATE. Won't say which country considering most of you are not to be trusted. Also still speculation lol but yeah.

There are some mirror websites (not likely safe though) or just same site name but different layout.
