Imagine receiving a $100,000 bill for hosting a simple static website. Yes, you read that right—a six-figure bill for what was supposed to be a low-cost, straightforward setup. This nightmare scenario happened to a Netlify user, raising questions about cloud provider pricing and the hidden risks of high traffic and Distributed Denial of Service (DDoS) attacks. This blog will break down what went wrong, why certain providers charge excessively for bandwidth, and how you can prevent this from happening to you.
What Happened?
A Netlify user recently shared their story about receiving a $100,000 bill for their website. The bill came as a shock because they were using a static site, typically an affordable option for hosting.
Expectation vs. Reality:
Static sites are known for their minimal hosting costs, especially on platforms like Vercel and Netlify, where monthly fees are generally around $20. However, these plans come with data usage limits; going beyond these limits incurs hefty charges, especially for bandwidth and compute costs.
The Incident: $100,000 for Excessive Bandwidth Usage
The user’s bill resulted from a massive spike in bandwidth, with around 60 terabytes of data transferred in one day. For context, Netlify charges $55 per 100 GB of extra bandwidth. At this rate, a single day’s excess data transfer pushed the bill up to $100,000.
Why Is Bandwidth So Expensive?
Comparing Cloud Providers:
Different providers charge vastly different rates for bandwidth:
- Netlify: $55 per 100 GB of bandwidth
- Vercel: Slightly more affordable at around $40 per 100 GB
- Hetzner: 20 TB of traffic is included, and additional traffic costs only €1 per TB
- Cloudflare: Offers near-zero costs for outbound data with its CDN services and R2 storage
The markup on some of these services can be 50x or more compared to traditional cloud providers like AWS or Hetzner.
Why the High Markup?
The elevated costs are partly due to SaaS providers’ pricing models, which often charge premium rates for data egress. They cater to users looking for convenience and don’t necessarily expect high traffic volumes.
The Risks of DDoS Attacks
In this case, the excessive bandwidth was likely due to a DDoS attack. DDoS attacks are challenging to mitigate because they involve multiple sources flooding a website with traffic, making it hard to distinguish between legitimate and malicious visits. Without proper protection, these attacks can drive up costs dramatically.
Lack of DDoS Protection and Mitigation Strategies
The user discovered that Netlify lacks automatic DDoS protection on its platform, a critical feature when handling unpredictable traffic spikes.
Cloudflare’s DDoS Protection:
Cloudflare offers an “emergency DDoS mode,” which displays a CAPTCHA challenge to users. This can absorb most of the attack traffic while allowing legitimate users to pass through.
What You Can Do:
If your provider doesn’t offer DDoS protection, consider adding a service like Cloudflare as a secondary layer. Alternatively, use providers with strong DDoS protections built-in to avoid the risk of high traffic spikes leading to enormous bills.
Netlify’s Response to the Incident
The response from Netlify was unusual. Instead of offering a direct solution, Netlify suggested hosting large files, like music or videos, on third-party platforms such as YouTube, Bandcamp, or SoundCloud to reduce bandwidth usage.
Why This Response is Problematic:
The whole point of using a static site host is to deliver files quickly and efficiently, including any media required for the site. Moving files to third-party platforms diminishes the flexibility of your website and goes against the original purpose of edge hosting.
Alternate Solutions: Hosting with Cost-Effective Providers
For developers dealing with high traffic or large media files, here are some more affordable alternatives:
- Hetzner: Low-cost bandwidth with included traffic allowances.
- AWS S3: Cost-effective storage and data transfer options, though charges can still add up.
- Cloudflare R2: Free egress bandwidth makes it ideal for hosting large files or handling high traffic.
Using a combination of these services can help keep your website’s operational costs in check.
Real Cost of a DDoS Attack: Beyond the Financials
For a developer outside high-income countries, such as in India, a $5,000 bill can be equivalent to months of savings or salary. The psychological toll can be substantial, especially if they’re experimenting or working on a side project.
Conclusion: Protect Yourself from Unexpected Costs
Here are some best practices to safeguard against unexpectedly high bills:
- Monitor Usage: Regularly monitor your bandwidth and serverless usage if your provider offers tracking tools.
- Enable Alerts: Set up alerts to notify you when you’re nearing your data limits.
- Consider Backup Hosting Options: Use reliable and affordable platforms like Cloudflare or Hetzner to host heavy assets.
- Implement DDoS Protection: Use providers with built-in DDoS protection or add an external solution like Cloudflare to minimize the risk.
Final Thoughts
This story had a positive ending, with the user’s bill eventually waived by Netlify after the incident went public. However, the event serves as a stark reminder of the hidden risks and potential costs of hosting a website. For developers, especially those hosting projects on a budget, it’s essential to be aware of the potential pitfalls and take steps to protect themselves.
