I hope that "managed host" got fired in a heartbeat and you moved elsewhere. Because they don't know WTF they're doing. As simple as that.

We did eventually move elsewhere because of acquisition. Of course those guys didn't even bother to run LACP and so our systems would regularly go offline for a bit whenever someone wanted to update a switch. I was a lot happier at the host that sometimes bumped the power cables.

Firing a host where you've got thousands of servers is easier said than done. We did do a quote exercise with another provider that could have supported us, and it didn't end up very competitive ... and it wouldn't have been worth the transition. Overall, there were some derpy moments, but I don't think we would have been happier anywhere else, and we didn't want to rent cages and run our own servers.
