Is ChatGPT Down Today? OpenAI Outage Reports Surface for Hundreds of Users as Trackers Show Mixed Signals

Some ChatGPT users reported trouble accessing OpenAI’s flagship chatbot early Sunday, with a tracking account estimating hundreds of affected users, though independent monitoring services showed the platform largely operational as of midday, illustrating the recurring gap between scattered complaints and confirmed, large-scale outages.

A post from the tracking account @status_is_down flagged the reported issue at 5:45 a.m. Sunday, asking followers whether they were also experiencing problems with ChatGPT or OpenAI more broadly. The scale and specific cause of Sunday’s disruption remained unclear as of publication.

Independent status trackers offered a mixed but largely reassuring picture of the platform’s overall health at the time. StatusGator, a service that monitors thousands of cloud services in real time, reported OpenAI as operational as of its most recent check Sunday morning, noting 23 user-submitted reports of outages over the prior 24-hour period, a volume within the range the service typically treats as background noise rather than a confirmed widespread failure. A separate check by the same tracker roughly seven hours earlier had similarly found OpenAI operational, logging 16 user-submitted reports in that window, with the tracker noting that an earlier smaller spike in complaints had already been resolved by that point.

UptimeRobot, which independently pings ChatGPT’s servers every five minutes from multiple global locations, reported no anomalies in its most recent automated check as of Saturday afternoon, finding no unusual response times or error codes. The service says it only flags ChatGPT as experiencing an outage after three separate confirmation checks from different global locations all detect a problem, a method designed to filter out issues tied to a single user’s device or local network rather than the platform itself.

OpenAI’s own official status page showed a mixed picture as well. The page referenced an issue affecting some users encountering 403 errors when loading or using ChatGPT conversations on iOS, an issue the company said it was investigating and would provide updates on as more information became available. It was not immediately clear whether that specific issue was connected to the broader outage reports referenced in Sunday’s social media post, or whether it represented a separate, narrower technical problem affecting only a subset of iOS users.

ChatGPT has a well-documented history of periodic outages since its 2022 public launch, with several notable incidents disrupting service for large numbers of users worldwide. In April 2026, ChatGPT experienced a partial outage that began around 10 a.m. Eastern time and left thousands of users globally unable to access the service, with reports on outage-tracking site Downdetector peaking at more than 8,700 in the United Kingdom and roughly 1,900 in the United States. OpenAI confirmed the “partial outage” at the time, later stating it had deployed a fix and was “monitoring the recovery” of the service, with most users regaining access within about 90 minutes.

That April incident affected a range of ChatGPT features, with user polling at the time indicating that difficulty accessing old conversations was the most commonly reported problem, ahead of separate complaints about being unable to sign in altogether. Additional outages have periodically affected specific ChatGPT features, including image generation, custom GPTs and the company’s Codex coding tool, according to tracking by outlets that monitor the platform’s status regularly. OpenAI has generally responded to such incidents with brief, limited public statements acknowledging that it is “investigating” a given issue, without always providing detailed explanations of the underlying cause, a pattern outside observers have noted as a recurring characteristic of the company’s outage communications.

Beyond individual outages, ChatGPT has also faced broader questions about reliability given its widespread integration into third-party products and services. Because a large number of businesses now rely on OpenAI’s underlying API to power customer-facing tools such as chatbots and automated support systems, disruptions to OpenAI’s core infrastructure can cascade into outages for companies that have built products on top of the platform, temporarily leaving their own customers without service until OpenAI resolves the underlying issue.

Users experiencing trouble with ChatGPT on Sunday were encouraged by outage-tracking services to rule out simpler explanations before assuming the platform itself was down. UptimeRobot’s guidance recommends trying to access chatgpt.com from a different browser, device or network, such as a mobile hotspot, along with disabling any active VPN, clearing the device’s DNS cache, or restarting a home router. If the site loads normally through one of those alternate methods, the tracker notes, the underlying problem is more likely local to the user’s own device or network rather than a confirmed platform-wide ChatGPT outage.

The service also cautions that even when its automated checks confirm a genuine outage, that does not necessarily mean every user is affected equally. Some disruptions are regional rather than global, some affect only specific features such as image generation or file uploads rather than the core chat function, and some manifest as unusually slow performance rather than a complete failure to load, complicating efforts by any single user to determine whether what they are experiencing reflects a broader technical problem or an isolated glitch.

As of Sunday, OpenAI had not issued a public acknowledgment specifically addressing the outage reports referenced in the morning social media post, and the company’s official status page did not reflect an active, company-confirmed incident tied to that specific report at the time of publication. The gap between individual user complaints and a formally confirmed platform-wide outage remains a common pattern across major online services broadly, with outage trackers generally relying on report volume crossing defined thresholds within short windows, combined with geographic clustering of those reports, before classifying an issue as a confirmed outage rather than a collection of unrelated, isolated problems.

The situation remains fluid, and further updates may emerge from OpenAI or independent outage-tracking services as the day progresses. Users continuing to experience access problems are advised to check OpenAI’s official status page directly for the most current information on any active incidents affecting the platform.
