Laravel Cloud + Cloudflare: Could a Huge DDoS Attack Cause Massive Bandwidth Charges?
We’ve been using Laravel Cloud for a few new client projects and, overall, we’re really happy with it. The deployment workflow is great, the zero-management approach is ideal for our smaller clients, and the CDN performance has been solid. Bandwidth pricing initially worried people when Laravel Cloud launched, but the changes made earlier this year seem to have fixed the biggest pain points, we haven’t seen anything scary on our invoices, and costs have been very manageable so far.
That said, our priority is cost control over uptime. These aren’t mission-critical systems. We want the benefits of the CDN and the streamlined developer experience, but if traffic goes completely crazy, we’d rather see the site fail than suddenly be on the hook for an unexpected bill.
Our apps typically scale to somewhere between 1–4 replicas, and even hitting 4 has never happened. Redis and MySQL are fixed-size, so the system naturally caps itself, this is intentional. Beyond normal usage we’re fine with it falling over.
Like everyone else, we got hit by the Cloudflare outage last week. It sent me down a rabbit hole reading Cloudflare’s blog posts, which led me to the article where they blocked a 7.3 Tbps DDoS attack — “37.4 TB delivered in 45 seconds.”
That number really stuck with me.
So here’s my question: What would actually happen if something like that hit a Laravel Cloud site?
Laravel Cloud sits behind Cloudflare, but Cloudflare isn’t physically inside the Laravel Cloud infrastructure, so even if most malicious traffic is filtered, what about the small percentage that gets through? With bandwidth at $0.10/GB, even a tiny leak from an attack that big could turn into a serious billing problem for a small client.
I know the chance is low, but DDoS attacks are rising (I remember seeing something like 200% year-on-year growth), so it doesn’t feel like a pure theoretical risk anymore.
I’m trying to understand realistically:
Would Cloudflare manage to block the bulk of this traffic?
I imagine a measurable volume would get through?
I asusme Laravel Cloud doesn't reimburse DDoS-triggered bandwidth charges if the attack somehow bypasses Cloudflare layers?
Is this something Laravel Cloud users should overly concerned about?
We’ve even considered adding a Cloudflare rule that just blocks the entire site once it hits a daily traffic threshold, basically a kill-switch to cap the worst-case bill. But that requires upgrading to get extra rule capacity, and I’m not sure if it’s overkill or totally unnecessary. Could we put our own CloudFlare Proxy in front of Laravel Cloud?
Would love to hear from anyone using Laravel Cloud in production or anyone who understands Cloudflare’s behavior at this scale.
