I’ve seen data centers go down for various reasons. Fire, flooding, cooling goes down, cut cables. In some cases servers are powered off to protect the hardware. SSG is dependent on the data center hosting company to resolve the issue before they can bring them back up. I don’t think SSG has the income to justify duplicate fail-over infrastructure in a separate data center.
Ahh, here it is again... the "poor, poor little indie studio SSG" card. That sympathy card has some serious, unwarranted miles on it.
Pro-tip - They're a multi-million dollar company (not even counting the LoTRO revenue) who's literal entire business is selling 1s and 0s.
If they haven't "justified" having a proper offsite failover plan then they have essentially "decided" they don't want to stay in business if/when they encounter a true DR scenario.
If they've outsourced their DC then a DR plan would be expected of the supplier. Or somebody hasn't procured right.
IT history is littered with the corpses of hosting companies who suddenly shutdown / failed virtually overnight.
Trusting your hosting provider to also be your DR site/planner is putting all of your eggs in one basket. Not a good idea.
Redundancy is one of the core tenets of DR planning. Diversity (in your service providers) is one of the core tenets of redundancy.
