About CMS
We track CMS (cms.gov) as part of the Health group. Live checks and user reports.
CMS has no official status feed we can read, so this page relies on our own checks and user reports.
What usually goes wrong with health services: patient portal and member sign-in failures, prescription refills or appointment booking not going through, and app errors.
Measured uptime from our checks: 100% over 1 day of checks. No public incidents logged since monitoring began 1 day ago.
Response time over the last 24 hours: 183 ms average, 37–1208 ms range across 79 successful checks.
Questions
Is CMS down right now?

We have not recorded a public CMS incident since monitoring began 1 day ago.

183 ms on average over the last 24 hours (37–1208 ms).
Does CMS have an official status page?

CMS not working for me but the status is fine. What now?
It is usually local: try another browser or the app, switch between Wi-Fi and mobile data, and clear the cache. For health services, watch for patient portal and member sign-in failures, prescription refills or appointment booking not going through, and app errors. If many people report CMS here at once, the problem is on CMS's side.
