  3. identified Nov 12, 2025, 04:24 PM UTC

    We’ve identified that these issues are being caused by inconsistent network routing between Europe and the United States on upstream providers. Semaphore’s systems remain healthy, but affected routes can cause slower file transfer and occasional connection timeouts.
