Pydantic Logfire Down? Real-Time Status & Outage Checker (2026)

Pydantic Logfire is a modern observability platform built specifically for Python developers, created by the team behind Pydantic. Logfire provides OpenTelemetry-native logging, tracing, and metrics with deep integration for FastAPI, Django, SQLAlchemy, and popular Python frameworks. With first-class Python semantics and a clean dashboard for structured logs and traces, Logfire has rapidly gained adoption among Python/AI engineering teams. When Logfire goes down, structured logs and traces are dropped and Python application observability fails.

This page provides real-time Pydantic Logfire status monitoring, historical uptime data, and instant outage alerts.

Our monitoring probes Logfire Cloud infrastructure every 60 seconds from multiple geographic regions:

• Logfire Dashboard — Web UI at logfire.pydantic.dev
• OTLP Ingestion Endpoint — OpenTelemetry span and log receiver
• Query API — Log search and trace retrieval
• Alert Engine — Threshold-based alerting
• SDK Connectivity — Python SDK authentication and data upload

How to Check if Logfire Is Down

Quick Diagnosis Steps

1. Check ezmon.com — Multi-region probes confirm ingestion vs. query failures
2. Test SDK connectivity — Run a minimal Logfire Python snippet
3. Check Logfire status — status.pydantic.dev for official incidents
4. Check OTLP endpoint — curl https://logfire-api.pydantic.dev/
5. Pydantic Community Discord — #logfire for real-time reports

Logfire Python SDK Health Check

import logfire
import os
import httpx

def check_logfire_status():
    """Check Pydantic Logfire connectivity and ingestion."""
    token = os.environ.get("LOGFIRE_TOKEN")
    
    # Test OTLP ingestion endpoint reachability
    try:
        resp = httpx.get(
            "https://logfire-api.pydantic.dev/",
            timeout=10
        )
        print(f"Logfire API reachable: {resp.status_code}")
    except httpx.ConnectError as e:
        print(f"Cannot reach Logfire API: {e}")
        return
    
    # Configure Logfire
    logfire.configure(token=token)
    
    # Send a test span
    try:
        with logfire.span("health-check", source="ezmon-probe"):
            logfire.info("Health check probe from ezmon.com", check_type="uptime")
        
        print("Logfire span sent: OK")
        
    except Exception as e:
        print(f"Logfire span failed: {e}")
    
    # Test FastAPI instrumentation (if applicable)
    try:
        import fastapi
        from fastapi.testclient import TestClient
        
        app = fastapi.FastAPI()
        logfire.instrument_fastapi(app)
        
        @app.get("/health")
        async def health():
            return {"status": "ok"}
        
        client = TestClient(app)
        resp = client.get("/health")
        print(f"FastAPI instrumentation: OK ({resp.status_code})")
        
    except ImportError:
        print("FastAPI not installed (skipping instrumentation test)")
    except Exception as e:
        print(f"FastAPI instrumentation check failed: {e}")
    
    print("Logfire: HEALTHY")

Logfire with FastAPI/Django

import logfire
from fastapi import FastAPI

# Initialize Logfire for a FastAPI app
logfire.configure()  # Uses LOGFIRE_TOKEN env var

app = FastAPI()
logfire.instrument_fastapi(app)

# Test that traces are flowing
@app.get("/health")
async def health_check():
    with logfire.span("health.check"):
        logfire.info("Health check requested")
        return {"status": "ok", "logfire": "connected"}

# Django integration
# In settings.py:
# import logfire
# logfire.configure()
# logfire.instrument_django(capture_headers=True)

# SQLAlchemy integration
# from sqlalchemy import create_engine
# logfire.instrument_sqlalchemy(engine=engine)

Common Logfire Issues and Fixes

Spans Not Appearing in Dashboard

import logfire

# Check if Logfire is configured
logfire.configure(
    token=os.environ["LOGFIRE_TOKEN"],
    # Enable console output for local debugging
    send_to_logfire="if-token-present",
    console=logfire.ConsoleOptions(
        min_log_level="debug",
        verbose=True
    )
)

# Force flush pending spans
import opentelemetry.sdk.trace.export as trace_export
# The SDK flushes on exit, but you can force it:
from opentelemetry import trace
provider = trace.get_tracer_provider()
if hasattr(provider, 'force_flush'):
    provider.force_flush(timeout_millis=5000)
    print("Spans flushed")

# Check OTLP export success
# Set OTEL_LOG_LEVEL=debug for verbose SDK logging

Token Authentication Issues

# Test token validity
curl -s "https://logfire-api.pydantic.dev/v1/info" \
  -H "Authorization: Bearer $LOGFIRE_TOKEN" | jq .

# Re-authenticate via Logfire CLI
logfire auth

# List projects
logfire projects list

# Switch project
logfire use my-project

# Generate new write token
logfire projects tokens create --project my-project

High Volume / Rate Limiting

import logfire

# Configure sampling for high-volume services
logfire.configure(
    token=os.environ["LOGFIRE_TOKEN"],
    # Sample 10% of spans
    trace_sample_rate=0.1
)

# Use span-level sampling for expensive operations
with logfire.span("expensive-operation", _sample_rate=0.01):
    # This span sampled at 1%
    do_expensive_work()

# Suppress noisy instrumentation
logfire.instrument_httpx(
    capture_headers=False,  # Don't capture request headers
    capture_request_json_body=False
)
