That tells me NOTHING about their staffing. Which means if something goes and they take too long to replace/fix the problem then it could results in more downtime than a lesser tier that have a more active staffing and so on.
I even seen people mentioning that it take their colocation facilities days to replace a PDU. When those should be replaced ASAP or within 24 hours if it only "semi" critical (like not displaying stats properly or such).
