Mastodon Incident Report / Root cause analysis:

Earlier today, users experienced timeouts with Search, Hashtags, and Autocomplete.

Root Cause: Our setup separates the Mastodon frontend VPS (Hetzner) from backend services (for example Elasticsearch) via an OPNSense firewall. Suricata (our IPS) triggered a false-positive on internal traffic and aggressively blocked the VPS IP, severing the connection to the search database.

Resolution: We identified the false-positive, added the frontend IP to the whitelist, and traffic immediately normalized. Everything is back to green!

Dialer Blocker, den man zwischen Computer und das Telefonnetz geklemmt hat, um zu verhindern, dass eine bestimmte Art von Schadsoftware (die Dialer) teuere Mehrwertnummern anwählen und horrende Kosten auf der Telefonrechnung verursachen.

Glücklicherweise eine Plage des frühen Internets, die heute nicht mehr relevant ist, da mit dem Aufkommen von DSL und Koax Verbindungen auch die Möglichkeit wegfiel, Telefonnummern direkt anzuwählen und analoge Modems und ISDN zunehmend an Bedeutung verloren.

Erinnert ihr euch noch daran? Unter der Domain „burningboard.net“, auf der heute eine Mastodon Instanz läuft, haven wir damals schon eine Community für Tech-Interessierte betrieben, nur auf anderer technischer Grundlage mit einem PHP basierten Bulletin Board und deutlich mehr Nutzern.
