Yes, that is right. We still see some people in another country doesn't affect with the coronavirus, and they still go to any place they want even for playing gambling in the casino. I think the online gambling site will not go offline unless their server gets an attack or have trouble, so that makes all of their services go offline. They can maintain the server from far, so they don't have to go to their office, and if something wrong happens, they can fix it in their place.
They know their business pretty well, they should have a business continuity plan and they won't just stop because the system is compromise, they have already anticipated all the possibilities as they are dealing with money, a day loss or offline is already equivalent to a big money and at the same time it could also affect the reputation of the site which gamblers might panic.
