BREAKING: Supabase Realtime Latency Issue Identified — Workarounds Available

Supabase experiencing significant Realtime latency affecting real-time subscriptions. Immediate workarounds and status checks included.

Incident Overview

Supabase is currently experiencing elevated latency in its Realtime service. Real-time subscriptions, presence tracking, and live query features are affected with delayed message delivery and subscription updates.

What's Down

Realtime subscriptions (database change notifications)

Presence tracking features

Live query updates across connected clients

Real-time broadcast channels experiencing delays (5-30+ second lag reported)

Standard REST API and PostgREST endpoints appear operational. PostgreSQL database connectivity remains stable.

How to Check If You're Affected

1. Monitor Supabase Status Page: Visit [status.supabase.com](https://status.supabase.com) for official incident updates 2. Test Realtime Connection: Subscribe to a test table and monitor message arrival times 3. Check Browser Console: WebSocket connection errors or reconnection loops indicate issues 4. Review Logs: Check Supabase dashboard → Project Logs for realtime service errors

Immediate Workarounds

1. Implement Polling as Fallback

```javascript // Replace realtime subscriptions with interval-based polling setInterval(async () => { const { data } = await supabase .from('your_table') .select('*') .order('updated_at', { ascending: false }); // Update UI with fresh data }, 5000); // Poll every 5 seconds ```

2. Disable Realtime Temporarily

Remove .on() subscription calls from your application

Rely on standard REST API calls and user-triggered refreshes

Manual "refresh" buttons provide better UX than broken real-time

3. Use WebSocket Reconnection Logic

```javascript const subscription = supabase .channel('your_channel') .on('postgres_changes', { event: '*', schema: 'public', table: 'your_table' }, payload => { console.log('Change received:', payload); }) .subscribe((status) => { if (status === 'SUBSCRIBED') { console.log('Connected'); } }); ```

4. Switch to Alternative Services

Firebase Realtime Database for critical real-time features

Socket.io with your own backend for presence/broadcasting

Pusher or Ably as managed alternatives

5. Reduce Realtime Load

Unsubscribe from unused channels

Limit number of concurrent subscriptions per user

Use server-side filtering instead of subscribing to entire tables

Recommended Actions

1. Immediate: Disable non-critical realtime features; implement polling fallback 2. Short-term: Monitor status page; use manual refresh UI patterns 3. Escalation: Contact Supabase support with project ID if issue persists 4. Documentation: Note incident time for post-mortem analysis

Status Updates

Note: This incident report was generated based on reported latency. For real-time status, check Supabase's official status page and your project's metrics dashboard.

I'm unsure about: Current mitigation ETA, whether this affects specific regions only, or root cause details — check official Supabase channels for confirmed information.
