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.
Co-Star website uptime and response time
Website responded successfully HTTP 200. Last checked 2026-11-08 15:14:56 UTC.
Checked address: https://www.costarastrology.com/
DNS lookup: 17 ms · TCP connection: 1 ms · TLS handshake: 4 ms. Certificate expires 2027-03-07; trusted connection: yes.

Median response time
228 ms
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.
0 consecutive successful checks within the last 30 minutes. These checks measure the public website; they cannot establish recovery of every feature.
Slowdown detection
More successful checks are needed to establish a response-time baseline.
Recent median: unknown · Earlier median: 128 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.
Infrastructure incident context
Check whether broader platform incidents coincide with the problem you are seeing. These providers are context, not verified dependencies of Co-Star.
No active incidents recorded.

About Co-Star status on Iszdown
Co–Star is an American astrological social networking service founded in 2017 and headquartered in New York City. Users enter the date, time and place they were born to receive an astrological chart and daily horoscopes that they can compare to those of their friends.
This page combines the available Co-Star report activity, official product status, public website measurements, and daily history. Each measurement has its own observation time. A search spike alone does not confirm downtime, and a reachable website does not establish that sign-in or every product feature works.
No mapped official components are available for this service. Latest public website measurement: 2026-11-08T15:14:56.000Z.
What to check when Co-Star is not working
These are troubleshooting suggestions, not a list of currently reported problems.
Co-Star 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.
Co-Star 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.
Website troubleshooting guide · Sign-in problems · API errors and timeouts
Include the time, affected feature, and error message when contacting official support. Keep passwords, payment information, session cookies, and access tokens private.
Recent Co-Star outage history
No product-matched official incidents have been archived for this service in the displayed history. This does not establish that it has never had an outage. See the daily calendar for other available evidence.
Frequently asked questions about Co-Star
Is Co-Star down right now?
Website reachable in latest check. The public website responded; signed-in features and APIs were not tested. This page was assembled at 2026-11-08T15:57:41.000Z.
How many Co-Star outage reports are there today?
The displayed rolling 24-hour window contains 0 recorded reports, from 2026-11-07T15:50:00.000Z to 2026-11-08T15:50:00.000Z. This is not a calendar-day total or a count of affected people. Estimated activity is shown separately as an estimate.
Why does Co-Star show operational when it is not working for me?
An official operational status can coexist with a local network issue, account problem, or feature-specific incident. Compare the mapped components, recent incident updates, and regional diagnostic on this page. Automated website checks test public access, not your signed-in session or every Co-Star feature.
When was Co-Star status last updated?
No current product status observation is available for Co-Star. Reports, estimated activity, and website checks can provide additional context.
Has Co-Star had outages before?
The daily calendar links available incident evidence and retains daily monitoring summaries. Pink marks service issues, green requires sufficient observations with no issues observed, and gray means insufficient coverage. The collected history is incomplete and is not a lifetime outage count or a guarantee of uninterrupted uptime.
How do I follow Co-Star or report a problem?
Use “Watch this service” to save Co-Star in this browser’s watchlist, then return to compare its status with other saved services. Optional browser notifications can flag status changes while the watchlist page stays open and visible; background alerts are not sent. Use the problem-report button for an outage report; contact the provider through its official website for account, billing, or private support issues. Iszdown is independent and cannot resolve provider support tickets.
