The International Music Score Library Project, also known as the Petrucci Music Library after publisher Ottaviano Petrucci, is a subscription-based project for the creation of a virtual library of public-domain music scores. Since its launch on February 16, 2006, over 495,000 scores and 59,000 recordings for over 152,000 works by over 18,000 composers have been uploaded. Based on the wiki principle, the project uses MediaWiki software, with an iOS app released July 10, 2018 and an Android app released March 28, 2019. Since June 6, 2010, the IMSLP also includes public domain and licensed recordings in its scope, to allow for study by ear.

## 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 [International Music Score Library Project on Iszdown](https://iszdown.com/now/imslp), 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. The public website responded; signed-in features and APIs were not tested.

No recent recovery can be established from available evidence.

## Website measurements

Successful sampled checks (24h): 100% (22/22). Restricted checks: 0. Median response: 94 ms. P95 response: 186 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.

## About International Music Score Library Project monitoring

This page combines the available International Music Score Library Project 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

### International Music Score Library Project 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.

### International Music Score Library Project 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 International Music Score Library Project 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 2026-11-08T19:08:46.000Z.

### How many International Music Score Library Project outage reports are there today?

The displayed rolling 24-hour window contains 0 recorded reports, from 2026-11-07T19:00:00.000Z to 2026-11-08T19:00:00.000Z. This is not a calendar-day total or a count of affected people. Estimated activity is shown separately as an estimate.

### Why does International Music Score Library Project 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 International Music Score Library Project feature.

### When was International Music Score Library Project status last updated?

No current product status observation is available for International Music Score Library Project. Reports, estimated activity, and website checks can provide additional context.

### Has International Music Score Library Project 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 International Music Score Library Project or report a problem?

Use “Watch this service” to save International Music Score Library Project 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.
