Uptime Monitoring for .onion Services

Standard uptime monitoring services operate on the clearnet and cannot reach .onion addresses. Even if they could, using a clearnet monitor to check a .onion service would require an exit from the Tor network, potentially compromising the hidden service's anonymity. Tor-native monitoring solves this:

• Monitor from within Tor — Health checks are performed through Tor circuits, same as your real users
• Accurate latency measurement — Measure response times as experienced by Tor Browser users, not clearnet users
• No anonymity leakage — Monitoring traffic is indistinguishable from regular Tor traffic
• Status page on .onion — Publish your status page as a hidden service so users can check availability without leaving Tor

This is essential for any organization running critical services on Tor — email, chat, file sharing, or web applications.

Deploy powerful monitoring solutions on AnubizHost's Tor infrastructure:

• Uptime Kuma — A beautiful, self-hosted monitoring tool with support for HTTP(S), TCP, DNS, and custom checks. Configure it to check .onion URLs through the local Tor SOCKS proxy.
• Cachet — An open-source status page system for communicating service status to your users. Publish incidents and maintenance windows on your .onion status page.
• Nagios / Icinga — Enterprise-grade monitoring with custom check scripts for .onion services via torsocks or SOCKS5 proxy.
• Custom scripts — Simple shell scripts using torsocks curl to check .onion endpoints and send alerts via encrypted email or Matrix.

Each monitoring server is configured with Tor pre-installed and a SOCKS5 proxy on localhost:9050 for all monitoring checks.

When a .onion service goes down, fast notification is critical. AnubizHost monitoring hosting supports multiple alert channels that preserve anonymity:

• Encrypted email — Receive downtime alerts via GPG-encrypted email sent through Tor
• Matrix/Element — Push alerts to a Matrix room accessible via .onion
• XMPP — Send alerts to XMPP accounts over Tor
• Webhook — Trigger webhooks on other .onion services for automated incident response
• Telegram (via Tor) — Route Telegram API calls through Tor for alerts

Combine monitoring with automated recovery scripts that restart Tor processes, clear caches, or failover to backup servers when downtime is detected.
