Cloudflare Pharmacy Issues: What Happened and How It Affected Online Pharmacies
Overview
On 18 November 2025, a major Cloudflare outage caused problems across large parts of the internet. Many online pharmacies, prescription platforms and medical services rely on Cloudflare to keep their websites fast, secure and available. When Cloudflare had internal issues, these pharmacy websites experienced errors, slow loading or complete downtime.
To help, this page breaks down what happened, why online pharmacies were affected, and what patients should do if they ran into issues getting treatment or placing orders.
What happened at Cloudflare?
Cloudflare acts like a security and speed layer for millions of websites. It checks traffic, blocks harmful requests and helps sites load quickly. On 18 November, one of Cloudflare’s internal systems overloaded and failed. This caused widespread errors on websites that depend on Cloudflare, including many pharmacy and health-service platforms.
Cloudflare confirmed that the incident was not caused by a cyber-attack. Ultimately, a sudden surge in traffic overwhelmed the system and caused the internal technical fault.
The impact of Cloudflare Pharmacy Issues on online pharmacies
Because so many pharmacies use Cloudflare, the outage caused several issues:
• Websites loading slowly or not loading at all
• Error messages such as 500 or 502
• Broken page elements, including checkout systems
• Login problems for patient accounts
• Difficulty accessing online consultations
• Verification and identity-check tools failing
• Payment pages timing out or refusing connections
These problems varied by pharmacy. Some were only affected for a short period, while others experienced longer disruptions, especially those heavily dependent on Cloudflare’s security tools.
Which pharmacy services were most likely impacted?
Pharmacies and consultation providers using the following Cloudflare features were most affected:
• CDN and caching (site speed)
• Firewall and bot protection
• SSL/HTTPS management
• API connections for patient records
• Cloudflare Access / Zero Trust login tools
• Pharmacy dashboards used by staff
If a pharmacy uses Cloudflare to power its entire website, any internal Cloudflare fault can cause immediate downtime.
Was patient data affected by Cloudflare Pharmacy Issues?
However, there is still no evidence that the outage exposed or compromised any patient data. This incident was a system failure, not a security breach.
Cloudflare’s issue was with uptime and stability, not with data security.
Online pharmacies continued to store data in their usual encrypted systems.
Cloudflare Pharmacy Issues: What to do if you were affected
If you were trying to place an order or complete a consultation during the Cloudflare outage, you may have seen unexplained errors. You can try the following:
- Refresh the page or try again later.
- Check the pharmacy’s social media or status page.
- If payment failed, check your bank — most failed sessions do not complete.
- If your consultation didn’t save, you may need to restart it.
- Contact the pharmacy directly if you suspect your order didn’t go through.
Most pharmacies will automatically resume normal service once Cloudflare stabilises.
Why pharmacies rely on Cloudflare
Many online pharmacies use Cloudflare for:
• Secure connections
• Fast global loading times
• Bot and fraud protection
• Traffic filtering
• DDoS protection
• API routing for patient and prescription systems
Because these services are essential for health-related websites, any Cloudflare outage can have a noticeable impact on patient access.
Will Cloudflare publish a full explanation?
Cloudflare typically releases a detailed post-incident report after major outages. This will explain the root cause and what they are changing to prevent repeat issues. Once this appears, we will update this page with more technical details.
