Response time

Where the time goes

"Is it down?" is usually really "it feels broken — what's wrong with it?" This is the answer: every millisecond of a request to x.com, broken into the four phases it actually spends time in.

This page is a Checkly monitor.

Not a mockup of one. Everything above is produced by the monitor below, running every 10 minutes from N. Virginia and Frankfurt. It lives in a repo, gets code-reviewed, and deploys from CI — the same way you would monitor your own service.

That’s the whole product. Monitoring you can read, diff, and version.

How we check X

A real request to the endpoint that matters, every 10 minutes — measured, not crowd-sourced.

What we actually do

  • We send a real HTTP GET to https://x.com every 10 minutes.
  • We run it from two datacenters: N. Virginia and Frankfurt.
  • It passes if the endpoint answers with a status below 400 within 10 seconds. Slower than 3 seconds is “degraded”, not down.
  • A single failed check isn’t a verdict. We retry it from the other region before recording anything, so a transient blip never shows here as an outage.

What a green check means

  • X answered a real request from both N. Virginia and Frankfurt — an actual measurement, not complaints counted from a crowd.
  • We probe the endpoint that fails when X fails, so a green check tracks the part you depend on, not a marketing page that stays up regardless.
  • Checks run around the clock, every 10 minutes, on the same infrastructure Checkly customers monitor production with.

Frequently asked

No. Our most recent check reached https://x.com and got a healthy response. We check every 10 minutes from N. Virginia and Frankfurt.

We run a real HTTP request against https://x.com every 10 minutes from N. Virginia and Frankfurt, using Checkly's synthetic monitoring. A check passes when the endpoint returns a status below 400 within 10 seconds. We are not counting user reports — we are measuring the actual response.

We probe https://x.com because it is the endpoint that best reflects whether X is actually usable.

We check X from N. Virginia and Frankfurt. If it answers us but not you, the problem is usually specific to your network, ISP, region, or account rather than X itself.

Downdetector counts user reports — how many people are complaining. We run an actual synthetic check against the service and report what the wire says. Reports lag the outage and can be noisy; a probe either gets a response or it doesn't.
