Even if your server does not have proper IPMI, most colo providers have an assortment of ip-kvms, you can ask for those and access your server from any modern browser.
I bet your provider has something like that. It's a godsend when you screw up, say, the hypervisor running state somehow and need bare metal access to unbork it :)
But I expect you're probably right some or all of the providers we use do have something like that, as I speculated in the previous post. I've just never understood the point of vga-type stuff when bios/uefi serial redirect exists and serial console is more convenient anyway once the kernel has started, so never asked the question.
