Popular communication platform Slack is experiencing a notification outage, leaving some users without alerts for new messages or struggling to find buried threads. The issue, which began on Monday morning, has been acknowledged by Slack, with the company logging an incident report and apologizing for the disruption to users' days.

According to reports from users, including those at The Verge, notifications are either not showing up or are delayed, making it difficult to keep track of conversations. Additionally, messages within threads are becoming harder to find, causing frustration among users who rely on the platform for collaboration and communication.

Slack's status page confirms that the issue is impacting threads, with the company stating that they are "currently investigating the issue and we'll be back when we have more information." While the cause of the disruption remains unclear, Slack has provided some updates, noting that other notifications should be working as expected, but threads may not be loading correctly.

In addition to the notification issue, some users are also experiencing trouble adding new members to multi-person DMs (group chats for up to nine people). This secondary issue has been logged by Slack, but it is unclear if it is related to the main notification outage.

Despite the visible spike on Downdetector, a website that tracks outages and downtime, very few reports have been logged, suggesting that the issue may be limited to a specific subset of users. However, the impact on those affected is still significant, highlighting the importance of reliable communication tools in modern workplaces.

The notification outage serves as a reminder of the importance of robust infrastructure and reliable uptime for platforms like Slack, which have become essential to daily operations for many businesses and organizations. As the investigation into the cause of the issue continues, users will be hoping for a swift resolution to minimize disruptions to their workflows.

This is a developing story, and we will provide updates as more information becomes available.
