KeyCDN should have an Auto Recharge Threshold that recharges when credits are under a certain amount other than $0.
For business-continuity, it’s incredibly dangerous that KeyCDN doesn’t recharge until the balance has already reached $0. If there’s a problem charging the credit card, the customer has VERY SHORT TIME to deal with this, or you get pushed off the internet.
If you combine this with any kind of emergency like being in the hospital, this will mean finding your CDN having been either suspended or actually deleted. If you use PushCDN, it also means having your content deleted, meaning that you can’t recover simply by paying the bill. If you have a real emergency or you’re dead, it means that someone else, maybe even a family member, now has to sort through setting up KeyCDN again.
We earn our living from our website, and a billing error combined with an emergency will destroy our finances. Please add the ability to recharge when the balance has hit $20 or $100 or $500 or some user-defined amount.
If business-continuity matters, this feature is essential, and it’s normal with pre-paid services.
