Across 2 notifications dated 2026-11-09T14:07:20Z through 2026-11-09T15:07:27Z, Tor Project Consensus Health Monitoring Mailing List reported a missing authority descriptor for moria1. These are reports from a monitoring feed; the notifications do not establish a continuous outage, its cause, or its operational impact.
Why it matters The repeated document checks provide a source-linked monitoring observation for further investigation; the cause and wider impact remain unestablished.

Correction · Corrected an unsupported claim that ordinary relay operators must edit their configurations. The cited issues request removal of bastet's existing entry from the software.
The Tor development team reported that the operator of the bastet directory authority notified them that the machine is very plausibly compromised. The report states that bastet will be removed from the source code because its keys can no longer be trusted. The operator is expected to generate a new identity for the authority.
Why it matters The report says bastet's existing keys can no longer be trusted and requests removal of its current entry from the software.
The Tor Project released version 0.4.9.16 as an emergency update specifically for directory authorities. The release addresses a 'thundering herd' issue caused by new required protover values in the previous release, which was causing older clients to exit. It also includes a workaround for a bug where old clients failed to handle unparseable microdescriptors correctly when TAP keys were omitted.
Why it matters Scope and consequences remain subject to the linked upstream discussion.
Following a period of packet drops and consensus delays affecting the maatuska directory authority, Tor 0.4.9.16 was released. The release introduced consensus-method 38, which reportedly eased pressure on directory authorities and reduced traffic from maatuska. Upstream network issues that contributed to the overload were also addressed during this period.
Why it matters The release of consensus-method 38 is intended to ease pressure on directory authorities.
The Tor Project released version 0.4.9.15, a security update introducing new defenses against large volumes of directory requests. The release makes the HSDir flag sticky across restarts and updates directory authorities to require specific protocol capabilities, rendering Tor versions 0.4.8 and earlier incompatible with the network. Operators are advised to upgrade relays as soon as possible.
Why it matters The release includes critical DoS mitigations for relays and enforces protocol changes that will disconnect older clients from the network.
Following a power outage on 2025-10-27, the Tor directory authority maatuska has been reporting substantially fewer relays with Guard flags in its votes compared to the network consensus. While initial reports showed a discrepancy of over 3,000 flags, recent data from November 2026 indicates the gap persists, with maatuska voting for roughly half the Guard relays of other authorities. The issue remains open.
Why it matters Scope and consequences remain subject to the linked upstream discussion.
