The Official Segment Status Page
Segment (acquired by Twilio in 2020) maintains an official status page at status.segment.com. It shows real-time status for each layer of the Segment Customer Data Platform:

Segment sits in the middle of your data stack. Understanding each step helps you pinpoint failures quickly:
Sources: Where Events Enter Segment
Events enter Segment from website (Analytics.js), mobile (iOS/Android SDK), server-side libraries (Node.js, Python, Ruby, Java, Go), or cloud sources (Salesforce, Zendesk pulled via Segment's ingestion). Each source has its own delivery guarantee — Analytics.js queues events in localStorage and retries for up to 72 hours.
Tracking API: The Ingest Gateway
All source libraries send events to api.segment.io/v1/(track|identify|page|group|alias). The API returns HTTP 200 on acceptance. A 200 response means Segment has received the event. Segment internally stores the event before routing it to destinations — this is the key difference from direct destination sends.
Connections: Routing to Destinations
Segment routes events to destinations in two modes: real-time (events forwarded within seconds) and batch (events accumulated and sent in bulk). Real-time destinations include most analytics and CRM tools. Warehouse destinations (BigQuery, Snowflake, Redshift) use batch mode. If a destination is temporarily down, Segment retries delivery for up to 4 hours.
Delivery Overview: Your Source of Truth
Segment's Delivery Overview dashboard (in each workspace under Connections > Sources > Delivery) shows per-event, per-destination success and error rates in real time. When diagnosing issues, check Delivery Overview first — it often shows destination-specific errors before they appear on the Segment status page.

status.segment.com →Check Segment Delivery Overview
Log in to app.segment.com, go to your workspace, and open Connections > Sources > [your source] > Delivery Overview. This shows real-time event delivery status and errors for each destination — often more granular than the status page.
Test the Segment Tracking API Directly
Send a test track event to the Segment API with your write key to confirm ingestion is working.
# Test Segment Tracking API (replace YOUR_WRITE_KEY)
curl -X POST https://api.segment.io/v1/track \
-H "Content-Type: application/json" \
-u "YOUR_WRITE_KEY:" \
-d '{"userId":"test-user","event":"Status Check"}'
# 200 OK = Tracking API working. Check Delivery Overview for destination delivery.X/Twitter Search
Search 'Segment down' or 'Segment CDP outage' on X. Growth engineers and data teams report Segment issues quickly.

These are the symptoms and errors you'll see when Segment is experiencing issues:
"Events not reaching Mixpanel / Salesforce / Amplitude"Segment Connections is experiencing delivery issues for that destination. Check Delivery Overview for error details — it shows whether the destination is returning errors (destination-side issue) or Segment is failing to connect (Segment-side issue). Segment retries failed events for up to 4 hours."Segment Tracking API returning 429 Too Many Requests"You are exceeding your plan's event rate limit. This is a configuration issue, not an outage. Implement batching in your server-side library to reduce the number of API calls. Segment's batch endpoint (/v1/batch) lets you send up to 500KB of events per request."Analytics.js not loading / script blocked"Segment's CDN (cdn.segment.com) may be blocked by ad blockers or content security policies, or the CDN is experiencing issues. Use Segment's API proxy or server-side tracking to bypass ad blockers. Check status.segment.com for CDN incidents."Engage audiences not syncing to Facebook / Google Ads"Segment Engage or the specific ad platform destination is experiencing issues. Audience syncs are batch operations that run on a schedule. Check Engage > Audiences > [audience] > Destinations for sync status and last sync time."Unify profiles not updating / identity stitching broken"Segment Unify (identity resolution) is degraded. User profiles will not be updated with new events, and audience membership calculations may be stale. Check status.segment.com for a Unify incident."app.segment.com not loading / 503 error"The Segment App UI is down. Event ingestion and destination delivery may still be working normally — the UI is a separate component. Check status.segment.com and use the Segment Public API for workspace management while the UI is unavailable.What to Do When Segment Is Down
Immediate Response
- Check status.segment.com — identify which layer (Tracking API vs. Connections) is affected
- Tracking API down: events may be lost — enable local event buffering in your server code immediately
- Connections down: events are safe in Segment — destinations will catch up on recovery
- Check Delivery Overview for specific destination error details
- Notify marketing/growth teams — Engage audience syncs and ad platform connections are paused
- Document the event gap window for data quality post-mortem
Long-Term Resilience
- Use server-side tracking with a durable queue (SQS, Kafka) upstream of Segment
- Archive all events to a data warehouse (BigQuery, Snowflake) in parallel — use Segment as a router, not the source of truth
- Use Segment Event Replay to backfill destinations from S3 archives after long outages
- Implement destination-level alerting in Delivery Overview for critical pipelines
- Consider RudderStack or mParticle as hot-standby CDPs for mission-critical pipelines
Frequently Asked Questions
Where is the official Segment status page?
Segment's official status page is at status.segment.com. It tracks the Tracking API, Connections (Destinations), Segment App UI, Unify, Engage, and Functions separately. Subscribe to email notifications to receive incident updates automatically.
Does Segment lose events during a Connections outage?
No — if only Connections is down, events ingested by the Tracking API are stored safely in Segment's internal storage and replayed to destinations when Connections recovers. Events are not lost; they are delayed. If the Tracking API itself is down, events that cannot be queued by your SDKs may be permanently lost.
How long does Segment retry failed destination deliveries?
Segment retries failed destination deliveries for approximately 4 hours after the initial failure. After 4 hours, events are discarded (not sent to the destination). For destinations that support it, you can use Segment's Event Replay feature to re-send archived events from S3 storage after the destination recovers.
Is Segment the same as Twilio Segment?
Yes. Twilio acquired Segment in 2020 for $3.2 billion. The product continues to operate as Segment (now under Twilio's umbrella). The status page at status.segment.com is separate from Twilio's main status page at status.twilio.com — check both if you use Segment and Twilio APIs together.
How does Segment compare to RudderStack for reliability?
Segment is the market leader in CDPs and has a mature, managed infrastructure. RudderStack is an open-source alternative that can be self-hosted (giving you full control over infrastructure) or used as a managed cloud service. For teams concerned about Segment reliability, RudderStack's self-hosted version eliminates vendor dependency at the cost of infrastructure management. mParticle is another enterprise alternative with a strong reliability track record.
