Telegram’s hosted api.telegram.org endpoint caps bot uploads at 50 MB and throttles concurrent media transfers. On BotFoundry, we size self-hosted C++ TDLib telegram-bot-api containers unlocking 2,000 MB local zero-copy file handling alongside Redis + PgBouncer Mini-App backends.

tg_cache:Telegram anchors its core webhook dispatcher and European user shards in Europe (DC2/DC4) while routing Southeast Asian accounts through Singapore (DC5). Selecting Frankfurt/London or Singapore minimizes TLS handshake round-trips.
Local telegram-bot-api writes every 500 MB–2,000 MB video transfer into /var/lib/telegram-bot-api. Schedule a systemd timer (`find /var/lib/docker/volumes/tg_cache -type f -mmin +360 -delete`) every 6 hours so temporary media never exhausts NVMe inodes.
Campaign traffic spikes send thousands of concurrent Mini-App requests; verify the HMAC-SHA256 initData signature once, issue a short-lived Redis session token, and front PostgreSQL 16 with PgBouncer transaction pooling.
Long-polling serializes update fetches and wastes idle sockets; terminating HTTPS on port 443 via Caddy with X-Telegram-Bot-Api-Secret-Token validation pushes updates concurrently to uvloop/Bun workers.
Yes — hosting static React/Vite Mini-App assets on a $2.95/mo ChemiCloud LiteSpeed plan leaves 100% of your Ubuntu KVM VPS memory and CPU dedicated to API and database workers.
Telegram dispatches HTTPS webhooks exclusively to ports 443, 80, 88, or 8443 backed by a trusted TLS certificate (such as automated Let’s Encrypt).
