Connectivity issues for some users (DNS, mostly Europe)

We've made some configuration changes that we believe should allow all impacted users to once again access Slack. Thank you all for your patience and help in debugging the intermittent and location-sensitive empty DNS responses that have plagued us this weekend. If problems persist and clearing your local machine's DNS caches does not fully fix the problem, please email feedback@slack.com for help.

Outage on slack.com

Between 7:52am PDT and 7:58am PDT Slack was serving 503 errors for 50% of all requests to slack.com. This was caused by a DNS misconfiguration and the change has now been reverted. The status.slack.com was also overloaded during this time and it may have been inaccessible.
