Test from another country
Is Slack blocked or down in your country?
Our main check runs from Newark, US. Run the same test from up to 3 internet providers in another country to see whether slack.com is blocked or broken there.
Probes by Globalping, a free network run by jsDelivr. One test uses up to 3 probes, home and mobile providers first.
For long-term evidence of website blocking, see OONI Explorer, where volunteers measure censorship around the world.

Frequently asked questions
Is Slack down right now?
At our last check from UtiBox server · Newark, US, Slack was up and answering normally. The page refreshes the check automatically.
What does Slack’s official status page say?
The official status page (slack-status.com) reports “Operational” for Slack. We read it every few minutes. It’s separate from our own check of the slack.com website above, so the two can differ.
Why is Slack not working for me?
If it’s up here but not for you, the problem is usually local: your connection, DNS, a browser extension, a VPN or a block on your network. Try the fixes on this page, then the Is It My Internet? check.
How do you check Slack?
Our server requests slack.com and looks at every layer: DNS, the connection, the TLS certificate, the HTTP answer, redirects and the page content. We also check it from up to 12 locations in other countries, using two free probe networks (Globalping and check-host.net), so a regional outage can show here too.
How often is this page updated?
A result is shared for 60 seconds when the site is up and 30 seconds when it has problems, then checked again. You can refresh it yourself after 30 seconds.
Can I get an alert when it’s back?
Yes. Use “Alert me when it’s back” and we’ll send one email when our check reaches it again. Guests confirm their address first.
