Maintenance ended

The broker upgrade is complete and message processing has resumed. Queued messages are now being drained; you may see brief delays as the backlog clears.

If you continue to see issues after this window, please reach out via Support WhatsApp.

Thanks for bearing with us.

The broker upgrade has been applied. Message processing has resumed and we're now monitoring the cluster to confirm stability before marking the incident resolved.

Queued messages are draining; you may notice brief delays while the backlog clears (typically within a few minutes).

We'll post the final update once the system is fully stable. If you observe persistent issues, please reach out via Support WhatsApp.

What's happening

Emergency upgrade of the messaging broker that powers internal communication between Zapster API services.

Why

Our infrastructure provider identified a memory leak in the current cluster version. The fix requires an immediate version upgrade — we'd rather act now than wait for an unplanned outage.

Impact

While the maintenance is in progress, message processing is paused:

• Outbound messages: API requests are still accepted, but messages are queued and won't reach WhatsApp until the maintenance ends.
• Incoming messages: messages from your contacts are held for processing.
• Webhooks: notifications to your webhook URL are paused and will be delivered retroactively once the service is back.

No messages are lost: queues are persistent and processing resumes from where it stopped.

ETA

Estimated over 1 hour, with no firm window yet. We'll update this incident as soon as we have a tighter ETA or when the service is restored.
