I'm only missing one thing out of your comments -- what will change for someone who spends over $10,000 per month across US, UK and HK on servers and hosting.
Is it time to move forward?? Will my hosting be affected??
If you have a stable codebase and infrastructure you can probably still keep using them, if you rely on their technical services heavily I would start looking around. I expect most of their good people won't be there for much longer.
In other words the services they provide you with will likely rapidly degrade.
