Honestly no — I didn’t feel it at all. The Pi was handling the spike silently in the background while I was working normally. Upload bandwidth on Eolo is 100Mbps, and a static Astro site serving mostly HTML/CSS is incredibly light. Peak day was 555 human visitors with 9.98MB total bandwidth — that’s nothing for a residential connection. The Cloudflare tunnel approach is smart especially without a static IP. We have a static IP included with Eolo (unusual for residential, I know) which simplifies things. For DDoS protection we rely on HAProxy on a separate Orange Pi Zero 3 doing rate limiting and our dynamic blocklist — but honestly at our scale a proper DDoS would still hurt. The “who knows about the future” concern about Cloudflare is real though. Building on free tiers of centralized services is convenient until it isn’t — which is part of why we went full self-hosted in the first place.
