# Network Time Protocol outage reports and status Canonical page: https://iszdown.com/now/ntpd Status: Website reachable in latest check 24-hour window (UTC): 2026-11-07T18:30:00.000Z to 2026-11-08T18:30:00.000Z Recorded outage reports in this window: 0 Last successful estimated-activity check: No usable observation available The Network Time Protocol is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware. NTP is intended to synchronize all participating computers to within a few milliseconds of Coordinated Universal Time. It uses the intersection algorithm, a modified version of Marzullo's algorithm, to select accurate time servers and is designed to mitigate the effects of variable network latency. NTP can usually maintain time to within tens of milliseconds over the public Internet, and can achieve better than one millisecond accuracy in local area networks under ideal conditions. Asymmetric routes and network congestion can cause errors of 100 ms or more. ## How to interpret this page Estimated down reports are based on US problem-related activity. Values are relative activity from 0 to 100, not counts of submitted reports. The HTML chart averages samples into ten-minute intervals. Partial samples are excluded and missing samples are not invented. Recorded outage reports and estimated activity are separate signals. Neither confirms that every user is affected. Missing or stale data does not establish that a service is working. Methodology: https://iszdown.com/methodology ## Citation Cite [Network Time Protocol on Iszdown](https://iszdown.com/now/ntpd), include your access time and the observation time above, and qualify estimated activity as an estimate. Recheck before describing current status. Iszdown is independent of the monitored provider. ## Estimated activity samples No usable activity samples are available for this service in this window. ## Evidence and recovery Website reachable in latest check. A public website resource responded; the application, sign-in, and APIs were not tested. No recent recovery can be established from available evidence. ## Website measurements Successful sampled checks (24h): 25.4% (15/59). Restricted checks: 0. Median response: 3555 ms. P95 response: 6181 ms. These are sampled public website checks from one US server, not continuous uptime or authenticated app/API tests. Missing data stays unknown. ## Daily outage history Dates use America/New_York. Green means no issues observed with sufficient monitoring; pink means official incidents, repeated website failures, or reports from at least three network addresses. Gray means insufficient coverage. These are daily evidence summaries, not guaranteed uptime. | Date | Daily assessment | Observed hours | Official incidents | | --- | --- | --- | --- | | 2026-10-19 | Service issues detected | 17 | 0 | | 2026-10-24 | Service issues detected | 21 | 0 | | 2026-10-26 | Service issues detected | 22 | 0 | | 2026-10-27 | Service issues detected | 22 | 0 | | 2026-10-28 | Service issues detected | 20 | 0 | | 2026-10-29 | Service issues detected | 22 | 0 | | 2026-10-30 | No issues observed | 22 | 0 | | 2026-10-31 | Service issues detected | 20 | 0 | | 2026-11-01 | Service issues detected | 24 | 0 | | 2026-11-02 | Service issues detected | 22 | 0 | | 2026-11-03 | Service issues detected | 22 | 0 | | 2026-11-04 | Service issues detected | 23 | 0 | | 2026-11-05 | Service issues detected | 23 | 0 | | 2026-11-06 | Service issues detected | 21 | 0 | | 2026-11-07 | Service issues detected | 23 | 0 | | 2026-11-08 | Service issues detected | 14 | 0 | ## About Network Time Protocol monitoring This page combines the available Network Time Protocol 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. ## Troubleshooting ### Network Time Protocol 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. ### Network Time Protocol 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. ## Frequently asked questions ### Is Network Time Protocol down right now? Website reachable in latest check. A public website resource responded; the application, sign-in, and APIs were not tested. This page was assembled at 2026-11-08T18:30:12.000Z. ### How many Network Time Protocol outage reports are there today? The displayed rolling 24-hour window contains 0 recorded reports, from 2026-11-07T18:30:00.000Z to 2026-11-08T18:30:00.000Z. This is not a calendar-day total or a count of affected people. Estimated activity is shown separately as an estimate. ### Why does Network Time Protocol 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 Network Time Protocol feature. ### When was Network Time Protocol status last updated? No current product status observation is available for Network Time Protocol. Reports, estimated activity, and website checks can provide additional context. ### Has Network Time Protocol 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 Network Time Protocol or report a problem? Use “Watch this service” to save Network Time Protocol 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. ## Service disruption activity Latest observation: 2026-11-08T18:19:54.000Z. Evidence index 0–100, not report counts, outage probability, or affected users. Missing periods are unknown.
