How to read this calendar
Dates use New York time (America/New_York). Green means no issues observed with sufficient monitoring coverage; it does not guarantee uninterrupted uptime. Pink includes official incidents, repeated website failures, or corroborated user reports. Gray days are unknown. Activity estimates alone do not turn a day pink. Today’s result can change.

95th percentile response time
0 failed checks; 0 restricted checks. Restricted checks are excluded from the success rate. Lines connect recorded samples across gaps; availability between checks is unknown. Response time measures receipt of HTTP headers, not full page load. Checks run from one US monitoring server and do not verify sign-in, API, or app features. These sampled results are separate from down reports and estimated activity.
Evidence behind the status
Website reachable in latest check. The public website responded; signed-in features and APIs were not tested.
Website checks and estimated activity have independent update times. Refer to each section for its latest observation.
These measurements describe different things. A reachable homepage can coexist with login or API failures. Missing evidence stays unknown.
Official component status
No mapped official components are available for this product. Parent-company status is not substituted for product status.
Official incident timeline
No product-matched incidents are available in the collected provider history. This does not prove that no incident occurred.
Recovery tracker
No recent recovery can be established from available evidence.
1 consecutive successful checks within the last 30 minutes. These checks measure the public website; they cannot establish recovery of every feature.
Slowdown detection
No sustained slowdown has been established against the earlier baseline.
Recent median: 372 ms · Earlier median: 506 ms. Flags require at least 3 recent and 5 earlier checks, more than twice the baseline, and at least 500 ms extra latency. Slowness alone does not identify server load as the cause.
Emerging down-report signals
No recent emerging problem patterns are available for this service.
Emerging problem patterns can persist after an incident and do not measure report counts or prove an outage.
Is it down in your region?
Run one public website check from a community probe. Results describe that probe, not every user in a country.
Results are reused for 15 minutes. Shared free allowance: up to 60 tests per hour. A successful website check does not verify authenticated app or API functions.

About A Certain Ratio status on Iszdown
A Certain Ratio are an English post-punk band formed in 1977 in Flixton, Greater Manchester by Peter Terrell and Simon Topping, with additional members Jez Kerr, Martin Moscrop, Donald Johnson, and Martha Tilson joining soon after. Drawing heavy influence from funk as well as disco and Latin percussion, ACR combined the post-punk Factory sound with the emerging influence of funk in indie music. "One of the first post-punk bands to get to grips with funk". The band were among the first to debut on Tony Wilson's Factory Records in 1979 with "All Night Party," produced by Martin Hannett. During ACR's early years with Factory, they scored seven Top Ten U.K. independent releases, highlighted by "Flight" and "Waterline," and released five albums beginning with The Graveyard and the Ballroom. Following late 1980s and early 1990s phases with major-label A&M and Rob Gretton's independent Robs Records, ACR were intermittently active.

What to check when A Certain Ratio is not working
These are troubleshooting suggestions, not a list of currently reported problems.
A Certain Ratio will not open
Compare your usual browser or app with a private browser window, then try another network if available. Save unsent work first. A difference between networks can help separate a local connection problem from a wider disruption.
A Certain Ratio is slow or only one feature fails
Record the affected action, exact error, and time. Compare the website response measurements with any official component incidents; loading a homepage does not test every feature.
