Is Stack Overflow down right now?
A live check of stackoverflow.com: we request its home page and tell you whether the server answered, with which status and how fast, and whether its HTTPS certificate is valid. If it is up for us but not for you, the problem is probably on your side of the connection.

Check another site
If Stack Overflow is down for you
Reload once, then try another network such as mobile data. If it works there, your connection, DNS resolver or a browser extension is the likely cause. If the check above says it is down too, the problem is the site’s, and waiting or following its status page is all anyone outside can do. The guides to HTTP and network errors explain each error message a browser shows.
Where the check runs from
One request from one location: Uptimely's own checker, outside your network. That is enough to tell a site that is down for everyone from one that is down for you, but it cannot tell a regional outage from a global one. A result is reused for up to a minute and refreshed in the background after that; the time of the check is printed beside it.

Is Stack Overflow down right now?
The check at the top of this page answers that: Uptimely requests stackoverflow.com from one location: Uptimely's own checker, outside your network, reuses the answer for up to 60 seconds and refreshes it in the background when you load the page later, and reports whether the server answered, with what status and how fast. The time of the check is printed beside the result. If it says up but the site does not load for you, the problem is most likely between you and the site rather than the site itself.
Where does Stack Overflow confirm its own incidents?
This page does not read an official Stack Overflow status feed, so the result above is Uptimely's own check of stackoverflow.com and nothing else. Stack Overflow's own channels, its status page if it publishes one and its support or social accounts, are where confirmed incidents and their updates appear.
What does a Stack Overflow outage usually look like?
Pushes, builds or API calls fail with 5xx errors or time out, dashboards load slowly or not at all, and webhooks arrive late. CI pipelines that depend on the service queue up or fail in a batch.
Why is Stack Overflow not working for me when the check says it is up?
The check runs from one location: Uptimely's own checker, outside your network, not from several regions. A site can be reachable from there and still fail for you because of your own network, your DNS resolver, a browser extension, an outage in your region, or a problem with your account rather than the whole service. Try another network (such as mobile data), clear the browser cache, and check the service's own status page for regional or partial incidents.
What does a 4xx or 5xx answer mean?
A 5xx status (500, 502, 503, 504) is a server-side error: the site is reachable but failing, and the check reports it as down. A 4xx status (403, 404, 429) means the server is up and answered, but refused or could not find the request. Some sites answer automated checks with 403 or 429 while working normally in a browser.
How can I get an alert when Stack Overflow goes down?
Create a free Uptimely account and add stackoverflow.com as a Website monitor. Uptimely checks it every minute and alerts you by email, SMS, phone call, Slack, Discord or browser push when it stops answering. The Free plan includes 10 monitors with no credit card.
Can I run this check from a script or an AI agent?
Yes. GET https://getuptimely.com/api/tools/check?url=stackoverflow.com answers the same check as JSON, or as Markdown with the header Accept: text/markdown. It needs no API key and allows 30 calls a minute from one address.
