Requests per week, measuredRequests per week, estimatedServer errors per week: 0

Every request to Linkbreakers QR codes and short links, per week, over 13 weeks. The last two weeks are counted from request logs. Earlier weeks are estimated from log volume, using the requests per log line measured in those two weeks.

## What this means for your QR codes - **Your printed codes keep working.** A QR code on a poster, a menu or a business card resolves every time it is scanned. - **Improvements never interrupt scans.** We ship updates often, and visitors never notice. - **Problems fix themselves.** If part of the service stops answering, traffic moves away from it automatically. ## Limits and caveats - The last two weeks are counted from request logs. Earlier weeks are estimated from log volume, so those bars are approximate. - Uptime is about Linkbreakers answering. Whether the website a link sends people to is up is outside our control. ## Frequently asked questions ### Do scans fail while you ship updates? No. A new version is ready and answering before the old one stops, so there is always a version answering. ### What counts as a server error? Any time our service fails to answer a request it should have answered. Requests for links that do not exist are answered with a "not found", which is the correct answer, not an error. ## Sources - Linkbreakers request logs
