URGENT: Bot Attack - 146GB Spike - Project at Risk of Pausing

Help

Hi Vercel Team and Community,

I’m experiencing an urgent situation with my project and need help:

Project: multivest-engine
Issue: Bot attack caused 146.7GB data transfer spike today (normal is <1GB/day)
Current Status: 146.92 GB / 100 GB (exceeded free tier limit)

What I’ve implemented (per Vercel support recommendations):
Attack Challenge Mode: Enabled (6 hours)
Bot Protection: Enabled
WAF Rules:

  • Rate Limit: 50 requests/minute per IP
  • Block Source Maps: Blocks .map file requests
  • Block Suspicious Bots: Blocks bot user agents
    robots.txt: Deployed to block unauthorized bots
    Source Maps: Disabled in production builds (GENERATE_SOURCEMAP=false)

The attack started today and I’ve implemented all protections. I’m monitoring Firewall logs and expect usage to drop significantly as the protections take effect.

My Request:

  • Can a grace period be offered while protections mitigate the attack?
  • Is there anything else I should do to prevent project pausing?
  • Should I expect immediate reduction in data transfer?

I’m on the Hobby plan and this is clearly an attack, not legitimate traffic. Any help would be greatly appreciated.

Thank you!

HI @thomas-6684, our team has prevented auto-pause on this team. Please keep the firewall measures in place and monitor usage regularly.
