Care to clarify to which platforms you have moved your clients? I've considered Linode, but haven't "pulled the trigger" just yet, and all this turmoil has me reconsidering. Thanks in advance.
I'm an ex-Linode customer also and hosted with them for years before switching (around the time that they were hacked via the Coldfusion exploit) and I agree, it's sad how far they've dropped from being one of the best in quality/support to what they are now. I can't tell if it's because they're trying to scale up too fast or if theres some other issue however.
Also, Linode is not really the "lowest-cost" option as Digital ocean and similar providers offer better deals for the low price VPS market.
