Amy Egan Hey there. I know this post is pretty old, but wanted to share some info in case it helps (hopefully you've already solved it). 3 million in seconds definitely doesn't seem like normal usage so that could be a DDoS attack. Whenever you see something like that happening, you can enable Attack Mode. It will challenge all visitors with a verification screen while allowing legitimate users through. It's free and requests blocked by it don't count toward your usage. You can also investigate traffic in your dashboard to see what's hitting your site. Look for patterns in user agents, IP addresses, or

system There's another community post with 404 debugging tips that might be helpful. Please give these solutions a try and let us know how it goes. community.vercel.com/t/debugging-404-errors/437 A human should be around soon to offer more advice. But you can also get helpful information quickly by asking v0.

Amy Egan Just tested it and saw it's returning a 404 with code NOT_FOUND rather than DEPLOYMENT_NOT_FOUND. That means the deployment exists, but the page you expected doesn't. Please use the debugging steps linked above to figure out why that's happening

Ryu Hi Devansh, If those Sentry events cluster around deploy times, I’d treat this as version skew first. With dynamic(() => import(...), { ssr: false }), the browser may not request that CSS/JS chunk until later. If the user loaded HTML/JS from an older deployment, then a new production deployment goes live, that old client can later try to fetch a chunk URL that no longer exists on the deployment it is being routed to. That usually shows up as: Loading CSS chunk failed /_next/static/css/<hash>.css A good way to confirm is to check the failed asset request in Sentry or browser devtools: status: 4

SkyMesh Dynamics ah, then I'm not the only one who reported this

Ryu Hi Yuze, Your openssl test is a good way to narrow it down. Since this fails when the trailing dot is included in SNI: echo | openssl s_client -connect deckclip.app:443 -servername 'deckclip.app.' but works without it: echo | openssl s_client -connect deckclip.app:443 -servername 'deckclip.app' then this is happening before your Next.js app or vercel.json redirects can run. So I don’t think there’s an app-level redirect/header fix for the HTTPS case. A trailing dot is valid in DNS as an absolute/FQDN form, but TLS certificate/SNI matching is a separate layer. If Vercel’s edge does not normaliz

Pauline P. Narvas Hey, @suheb! Feel free to share more details about your project, it'd help us tailor our suggestions, but some ideas to get you started: Bundle Size Optimization Use <@next> /bundle-analyzer to identify large dependencies: ANALYZE=true npm run build Enable optimizePackageImports in next.config.js for icon/utility libraries Implement code splitting and lazy loading for non-critical components Tree-shake unused code and remove unnecessary dependencies Image Optimization Use Next.js <Image> component for automatic optimization Images are served in modern formats (WebP/AVIF) reducing size by 25-35

Ryu A good way to approach this is to separate build/deployment size from runtime loading performance. For deployment/build size: Remove unused dependencies. Check for large assets accidentally included in the repo. Avoid bundling server-only packages into client components. Use dynamic imports for heavy UI/client-only code. Keep generated files, uploads, and local cache folders out of the deployment. For page performance: Use next/image for images. Compress large images before uploading them. Lazy-load below-the-fold components where it makes sense. Check bundle size with a bundle analyzer. Use V

Pauline P. Narvas In most cases, if you exceed your usage limits on the Hobby plan, you will have to wait 30 days before you can use the feature again.

mwask will all my projects be paused???

Longnguyenthanh075 5963 I am having the same issue as I approaching end limits of 10GB, the document said up to 10GB for Hobby plan and no mention of resetting as well. I am well past that 30-day period but have not see it resets. I checked with the CS bots from vercel it said the limit will be resetted.

Naimusshakib582 Pixel "Thank you, Pawlean, for the detailed troubleshooting guide. I have followed the steps you provided, but I believe the issue is related to Edge Network Routing rather than a standard 404 configuration error like a missing index.html or an incorrect build output. Here are the relevant details based on your guide: Domain Configuration: My domain shows a 'Valid Configuration' status in the Vercel dashboard. Observed Error: I am getting \[Mention the exact error here, e.g., a browser-specific DNS Error/No Response, OR the Vercel white 404 screen with its specific Code and ID if you see it\]. It se

Anshuman Bhardwaj Hi @ahmadsajid3470-5358, I'm happy that you're considering Vercel for your project. I think you can find some of the biggest New Media outlets on our vercel.com/customers page. If you optimize and cache your content properly, I think Vercel can take you very far. Let me know if you have specific questions.

Selçuk Çukur Yes, Vercel is definitely suitable for a gaming content and news site like yours. Since most of your pages are static (guides, updates, blog posts), Vercel’s global CDN will serve them super fast to visitors everywhere. Performance: Static content is cached at the edge, so even during traffic spikes after big game updates, pages load quickly. SEO: If you’re using Next.js or similar, server‑side rendering and fast response times help search engines index your content properly. Traffic handling: You don’t need to worry about scaling servers — Vercel automatically handles spikes in traffic. CDN:

Ahmad Sajid Thanks man this helps me.

Emma Taylor Great overview, thanks for sharing this. One thing I’ve noticed with Vercel is how much the edge network and image optimization help without extra configuration. Even basic projects feel faster once deployed. The preview deployments are also really useful for testing changes before going live, especially when working in a team. It reduces a lot of guesswork. This kind of summary is helpful for people who are new to Vercel and trying to understand where the performance gains actually come from.
