Public watchtower directory
No signup · no API key · static99 towers listed · 85 probed hourly · 1 responding · 14 speak another protocol · swept 6 min ago
Every row carries the URL where its address was published. A tower whose provenance we cannot show is not listed. The finding is the shorter version of this table.
What a probe proves
The tower answered on its published address, completed the handshake against its published key, negotiated a session for a real channel type, and acknowledged an encrypted update we uploaded. We then deleted the session. Measured hourly from a Lightning node we run, and published here.
What no probe proves
That the tower would broadcast a justice transaction if your counterparty published revoked state. That takes a real breach, on mainnet, with a real channel. Nobody publishes that data. Neither do we. Anyone claiming to verify watchtower efficacy without paying for breaches is guessing.
What “accepted” and “acknowledged” mean
The watchtower protocol has eight messages and none of them returns a stored blob — a tower only ever hands the data back to the chain, on a breach. So no client can read its own backup back, and neither can we. Stored is the tower’s claim; acknowledged is ours. We upload an update rather than stopping at the session because a tower whose disk is full will negotiate a session quite happily and then fail to store — that failure is visible and we report it. A tower that acknowledges an update and then loses it is not distinguishable from one that keeps it, by us or by anybody.

not responding — no attempt negotiated a session
no data — no completed attempt
intermittent — some attempts did
responding — every attempt did
The legend is in rank order — act, unknown, watch, nominal. A blind spot outranks a measured deviation, which is why no data sits above intermittent and is never rendered as a failure. The table itself is sorted working-first for the reason below.
Default order is working first. Everywhere else in this product a list of states is ranked worst-first, because a health screen answers “what needs me”. This table answers “which tower should I use”, and putting 84 dead towers above the 1 live ones would bury the only rows anyone can act on. Sort any column to override it.
A tower published at more than one address is one row, not two — a tower is its key. Its figures are those of its best-performing address, and the addresses it does not answer on are listed beneath it. An address that answers on TCP while the key published for it does not is a stale listing rather than an outage, and is marked as such.
