Is fortrabbit down?

We are looking into issues for Let's Encrypt certificates that have been recently created or renewed.

We think to have resolved the certificate issue. It was related to a change in Let's Encrypt root chain certificate. This is something, that is not happening on a regular basis, so it was not included with general security monitoring of external sources. It affected only a small number of newly created or recently updated certificates. Contact us if you still see SSL issues.

We are looking into web delivery issues for about 30 Apps hosted in the EU region of the old platform. The issues may have started around 06:00 UTC. Not all Apps are down, just some, they return random errors or timeouts.

Post mortem Universal Apps run shared host systems. These host systems have - of course - limited file storage. Initially we enforced hard file system quotas, but an underlying bug in BTRFS caused issues with that. So we lifted the hard limits and allowed exceeding the including file system limits. For Universal Apps, there is no automatic scaling, so that solution is actually better for clients too. We overbook storage, roughly by the factor of three, which would allow clients to use as twice as storage as the largest Uni plan. We regularly check for Apps that are exceeding the limits and write mails. Lately we have to do that more often. Most commonly, excessive file storage usage is attributed to code/config misconfiguration. Most often find a lot of old local backups files (maybe some plugin?), but also a lot of cache files. Specifically the later is getting an issue more and more. Maybe because of bots more aggressivly crawling websites, that offer an unlimited number of possible pages. We have health checks in place, alerting us on storage issues. In this case, the storage filled quickly, causing all kind of random errors. We pro-actively removed cache folders, which caused higher load on the host system, when Apps refilled the caches. This architecture is of course not prefect. It's one of the many reasons we decided to create a new platform from scratch. The new platform solves this on multiple levels: Larger storage plans Optional "Autoscaling": either capped, or upgrade After monitoring, we consider the issue now resolved.

The App website screenshots in the dashboard are currently broken, always returning an image of a standard 404 error. As we planned to introduce website screenshots for the new platform as well soon, we plan to have the new websites screenshot service to serve both platforms, new and old. Until then, please allow us to not serve website screenshots. We hope to have website screenshots for new and old platform back in May.
