Softlayer is the name you're thinking of. They were pretty decent 10 or so years ago, but never touched them after the IBM acquisition.
Two years ago I had to help a customer debug some weird nginx behaviour, resulting in their traffic spiking at ten times the expected rate. The IBM/Softlayer VPN required that I used Internet Explorer, but it still failed to work. We spend three month with IBM and IBM Cloud consultants to make it NOT work.
IBM destroy everything it buys. They have POWER, their mainframes and associated software left. How that keeps them afloat is a mystery.
As an example, most network or server changes you made through the API resulted in an automated email saying your sales representative would be in touch about your order, followed a minute later by an automated email saying the change was done at $0 charge.
