Live monitoring · Last check
Every few seconds our servers in us-east load another website and record whether it answered, how fast and with what code. Nothing on this page is typed by hand: it is what our checks see right now.

Every website we monitor, one dot each, most popular first. A dot lights up when the live feed checks it.
1,510 websites block automated checks (a bot wall, a country block or "access denied"). We say so on their pages and rely on what people report. A blocked check never counts as an outage.
Confirmed by 2 failed checks in a row.
Every check our servers made, per hour.

Some problems
A check is only as good as the connection it runs on, so we check ourselves too.

If 3 of these 5 fail at once, the problem is on our side: results are kept but change nothing until they pass again.
A site is marked down only after 2 failed checks in a row, and if more than 5% of sites seem to fail at once we check again before marking any of them down.
The 10 most popular websites are checked every 15 minutes, the next 900 every 30 minutes, the rest every 2 hours, and any site people report every 5 minutes.
6,305 websites. Search, filter and open any one for its full history.

Updated every minute. Times are UTC. Field names stay stable; uptime and outages count only outages confirmed by 2 failed checks in a row.
The 10 most popular websites every 15 minutes, the next 900 every 30 minutes and all others every 2 hours. As soon as people on 3 or more networks report a website, we check it every 5 minutes until an hour after the last report.
The website blocks automated visitors with a bot wall, a country block or an "access denied" answer. That says nothing about whether it works, so we never count it as an outage. Its status page relies on what people report instead.
No. We load the home page only. Login, payments, apps and other parts of a service can fail while the home page works, which is why user reports always count on their own.
From our own servers in us-east. Every check identifies itself as our bot, requests one page, and never logs in, submits forms or follows links.
