Features like unfurling links and other service integrations (including email, calendar, etc.) are delayed and/or slow. Our Ops team is working on resolving the issue. We apologize for any inconvenience.
Users may experience problems logging into some teams. Users who are already signed in should be able to continue using Slack, though the quality of service may be degraded. Our Ops team is investigating the issue!
We've reverted a code change released at 9:23am PST that caused login requests to get very slow and have observed that teams are once again able to login. The change that was reverted introduced a dependency on our search infrastructure at login which was unnecessary and has now been removed.
We're investigating reports from several large customers that they are unable to login to Slack. We'll post more details here as soon as we can.
What is this site?
We continuously monitor the status of slack.com and all its related services. If there are any interruptions in service, a note will be posted here. We will also post notices of scheduled downtime on this page.
Slack is a distributed platform and during any given incident it is rare for all Slack teams to be affected. For this reason, we report our uptime as an average derived from the number of affected users.
If you are experiencing problems connecting to Slack and do not see a notice posted, please email firstname.lastname@example.org. Follow us on Twitter for status updates.
