Starting on October 5, 2020 at 5:58 a.m. PDT, some customers experienced degraded functionality in Slack due to slow API performance. Since many of Slack's features rely on making API calls, customers experienced latency in almost all aspects of our service. Slack is the collaboration hub that brings teams and tools together. In this Slack demo, you'll see how work happens in Slack. Slack brings team communication and collaboration into one place so you can get more work done, whether you belong to a large enterprise or a small business. Check off your to-do list and move your projects forward by bringing the right people, conversations, tools, and information you need together. Slack is available on any device, so you can find and access your team and your work, whether. Slack used to have a way for me to generate a link that would last for a while (at least for each 1000 people), but not anymore - now the link changes too often so I had to create this separate page so whenever the link expires, I only have to update the link once.

Issue summary:
Starting on October 5, 2020 at 5:58 a.m. PDT, some customers experienced degraded functionality in Slack due to slow API performance. Since many of Slack's features rely on making API calls, customers experienced latency in almost all aspects of our service. Efi pin unlock. This included, but wasn't limited to, the sending and loading of messages in threads and channels, as well as searching, calling, and accessing administrative features.
We initially identified an overloaded database memory cache server as a source of instability. At 8:10 a.m. PDT, we provisioned a replacement server for this host. When it came online, it unexpectedly caused additional instability and further degraded the performance and availability of our API. The replacement server came fully online with no residual instability in our database memory cache layer by 8:52 a.m. PDT.
While we were working on the previous memory cache issue, our team also began looking into problems with our internal service discovery system. This system is responsible for routing traffic within our infrastructure to the multiple services that support various features of Slack. We made several changes to this system over the course of the next several hours to remediate the impact of its instability. Throughout this time, our service was degraded, but was still available.
At 1:25 p.m. PDT, one of these configuration changes inadvertently degraded Slack's availability further and triggered an outage. We immediately identified and deployed a fix for this issue, which finished rolling out to our server fleet at 1:38 p.m. PDT. At this point, we determined the system was fully recovered and operating normally for all customers.
Around 5:00 p.m. PDT, we received reports about portions of the product that were still impacted by ripple effects from the earlier disruption in our service discovery system. This included search, which we remedied at 5:40 p.m. PDT. We also saw lingering errors in applications using our Real Time Messaging (RTM) API, and resolved those problems by 10:30 p.m. PDT with similar remediation steps.
Our teams have been working around the clock on ensuring that Slack remains available, fast, and reliable. While we haven't yet resolved all the underlying nuances of the degradation in our service discovery system, we're confident that we have a path forward and that we have proper mitigations in place to continue this work. Doom steam badge. We don't expect any additional customer impact due to this issue. However, if similar problems do arise, we'll provide updates on this site. If you would like to receive a full Root Cause Analysis (RCA) report, please reach out to feedback@slack.com to request one. Understanding and remediating this issue has our full attention — nothing is a higher priority — and we'll send the report to you once it's ready.
