You will get better customer support from Vercel. Cloudflare gives almost zero customer support if you are pay-as-you-go plan.
There’s also the community forums although I find it’s harder to stay on top of those personally.
Not trying to say our paygo support is as good. Just saying for those customers, I do personally try to offer ENT-level support as an entire class of users (ie all paygo = 1 ent to me for the products I personally support)
Most of the engineers and product leaders on the teams that make the services check those channels daily and jump into help where they can. There's also a huge community of power users there called Community Champions who help out as well.
I wish this never had to be said, it shouldn't be a secret.
