It's still down.

18 days and counting. I'm getting notifications about impending domain registration expirations due to the billing failures. No response to urgent support tickets. Oy.

"These customer accounts may also be downgraded temporarily, unable to add new sites, and unable to purchase/transfer/renew domains."

Not renewing domains? Sounds critical.

I haven't been able to add a website to cloudflare since a week now. It has been affecting core business but it seems this issue is not on Cloudflare's priority list.

Can you email me (jgc @ cloudflare) about this.

Cloudflare's billing has been experiencing outage since a week now affecting the services and disrupting business. I have been suggesting Cloudflare to my clients only for it to stop working and causing embarrassment.
