Uptime monitoring from 15 cities on 4 continents
BBoxProbe is an uptime monitoring and status page service. It checks your sites from cities around the world, alerts you when they go down, and gives your customers a status page.
Free for 5 monitors and 1 status page, no card. We email you a link to sign in; there is no password.
Some cities see errors
API errors from Singapore
Investigating, 14:04 UTC: API requests from Singapore time out. The other cities are normal.
How alerts work
One city's network trouble shouldn't wake you up. By default a monitor counts as down when more than half of its cities fail, and at least two when it checks from two or more.
How multi-region alerts workEach round, every city you picked for the monitor checks it: a page, a port or a domain.
A city counts only when two rounds in a row fail, so a single blip passes. You can make it one round per monitor.
The monitor is down when enough of its cities agree. You can set how many per monitor.
It names the cities and what they saw, by email, Slack, Discord or webhook. Another one follows when it's back up.
2 of 3 cities failed two rounds in a row; 2 are needed. Down.
Sent by email, Slack, Discord or webhook
API is down
Frankfurt and Singapore get 502 Bad Gateway.
Down since 14:04 UTC.
We'll email again when it's back.
Set a response time per monitor. You get an alert when more than 20% of checks are slower than that for 30 minutes.
A monitor that keeps going down and up sends one notice, not a stream, and another once it has been stable for 1 hour.
Set an objective, like 99.9% over 30 days. You hear when errors use up its budget too fast, even while it isn't down.
For HTTPS and TLS ports: an alert 14 days before a certificate expires, and again at 7.
What you can check
A monitor is one address, checked from the cities you pick. Three kinds cover most of what can go down.
How each check worksUp when it answers with an expected status code (any 2xx unless you list others) and passes the text checks you set.
https://example.com/health
For a database, a mail server or any other port. Up when it accepts a connection, and completes the TLS handshake when TLS is on.
example.com:443
Up when the domain resolves with at least one record of the type you pick.
example.com
A new monitor starts with Frankfurt, Virginia, and Singapore, one each in Europe, North America, and Asia, so a regional outage shows as one city down. Pick the cities you want: up to 3 on Free and all 15 on Pro and Max.
Resolved 14:31 UTC
Requests from every region succeed again. A postmortem follows.
Monitoring 14:22 UTC
A fix is out. We're watching the error rate.
Identified 14:13 UTC
A bad deploy on the Singapore edge. Rolling it back.
Detected 14:04 UTC
API is down.
Status pages
Every plan comes with one, at bbox.to/your-name, or at your own domain on Max. It shows your monitors as the checks see them, so you don't have to update it by hand while you fix things.
Everything a status page doesA monitor that's down shows as an incident, marked Detected until you post an update.
Post Investigating, Identified, Monitoring and Resolved updates, then a postmortem.
It shows as maintenance, not an outage, and alerts for those monitors stay quiet.
Visitors subscribe and confirm by a link; they hear when an outage starts, ends, or gets an update.
An Atom feed for feed readers, JSON for your own tools, and a badge for your README.
