Direct answer
Direct Answer — Turnitin, like any major online platform, occasionally experiences outages, slowdowns, and technical errors that prevent students from logging in, submitting papers, or accessing reports. These problems often spike during peak submission hours (typically evening deadlines) and can be caused by server overload, browser compatibility issues, or scheduled maintenance. Most Turnitin outages are resolved within 1–4 hours, but knowing what is happening and what you can do in the meantime is essential for meeting your deadlines.[1]
Is Turnitin Down Today? Common Outages and Error Reports
When students search "Turnitin problems today," they usually want to know whether the platform is experiencing a confirmed outage. Checking the official Turnitin service status page is the most reliable way to confirm whether an incident has been reported. That page tracks component health across Turnitin's core services, including the Submissions API, Similarity Report Generation, AI Writing Detection, and User Authentication. When a component shows degraded performance or an outage, Turnitin typically posts an update with an estimated resolution time.[2]
According to user report aggregators, Turnitin problems follow predictable patterns. Website-related issues account for roughly 40% of all complaints, followed by login problems at approximately 35%, and file upload or submission errors at around 25%.[1] The most common user-reported error messages include "Server Error (500)," "Unable to log in," and "Submission failed after loading." These problems often coincide with high-traffic periods, particularly during the evening hours when assignment deadlines fall due across multiple institutions.
Historical data from Turnitin's official incident reports shows that most outages are resolved within one to four hours. Common causes include elevated error rates on the Submission API, database connectivity issues, and scheduled maintenance windows. Turnitin typically performs maintenance during off-peak hours to minimize disruption, but unexpected infrastructure problems can still occur without warning.[2]
Why Is Turnitin Giving Me an Error When I Try to Submit?
Submission errors are among the most frequently reported Turnitin problems, and they often have straightforward causes that students can fix themselves without waiting for a system-wide resolution. One of the most common issues is file-related: Turnitin accepts a limited set of file formats (.docx,.pdf,.txt,.pptx,.xlsx, and.odt), and files must not exceed 100 MB. Attempting to upload unsupported formats, overly large files, or corrupted documents will produce an immediate error message.[3]
Browser and network issues are another major source of submission errors. Turnitin recommends using Chrome or Firefox with cookies and JavaScript enabled. Safari, Edge, and older browsers may cause compatibility problems that prevent the upload from completing. If you encounter a "Submission Failed" message, the first troubleshooting step is to clear your browser cache and cookies, then try again in an incognito or private browsing window. Unstable Wi-Fi connections can also cause timeouts during the upload process, so switching to a wired connection or a more reliable network may resolve the issue.[3]
Less obvious causes include unsupported characters in the document, corrupted embedded fonts, or special formatting that Turnitin's parser cannot handle. In these cases, copying the text into a clean plain-text document and then reformatting it as a.docx file often resolves the error. If the problem persists after trying these steps, it may be a server-side issue rather than a local one, and checking the official status page for confirmed incidents is the next logical step.[2]
FAQ
Q: How can I check if Turnitin is actually down versus having a local issue?
A: The best approach is to check both the official Turnitin status page (turnitin.statuspage.io) for confirmed incidents and Downdetector for real-time user reports.[1][2] If the status page shows all systems operational but Downdetector shows a spike in user reports, the issue may be localized or intermittent. You can also ask classmates or check your university's IT portal to confirm whether others are experiencing the same problem.
Q: What should I do if my Turnitin submission fails right before the deadline?
A: First, try the quick fixes: clear your browser cache, switch to Chrome or Firefox in incognito mode, check your file format (.docx or.pdf) and size (under 100 MB), and ensure you have a stable internet connection.[3] If these steps fail, take a screenshot of the error message, email your instructor explaining the issue, and attach your paper to the email as proof of timely completion. Most instructors will accept this during a confirmed outage.
Q: Can I use a different service to check my paper while Turnitin is down?
A: Yes. Several third-party services generate real Turnitin AI and similarity reports that match what instructors see in their institutional systems. These services allow you to preview your AI score and similarity percentage even when Turnitin's main platform is unavailable, so you can make revisions before submitting through your university's system.
Q: Does Turnitin detect AI writing in all parts of a document?
A: No. Turnitin's AI writing detection analyzes only prose text within the document. It does not examine bullet points, tables, code blocks, references, or author names.[4] This means a paper with significant technical content, tables, or code may return a lower AI percentage regardless of how the text was generated.
Q: Why does Turnitin show an asterisk (*%) instead of a specific AI score?
A: In Turnitin's AI writing report, any AI detection score below 20% is displayed as an asterisk (*%) rather than as a specific single-digit percentage such as 3% or 12%.[4] This is a deliberate design choice by Turnitin to avoid over-interpretation of very low scores. The only explicit low numeric outcome a student typically sees is 0%; otherwise, sub-20% results fall into the asterisk category.
