We have been seeing some really weird storage performance with the R2 server lately up to and including short outages such as the one the server just now experienced.
This server has been online for quite some time and has not had a file system check performed in a while. We believe the issues faced are related to some file system corruption that needs to be corrected.
We are scheduling emergency maintenance for the R2 server for tonight, September 27, 2019 at 11:30 PM Eastern Time [GMT-4]. We expect the file system check to take no more than 15 minutes but we are going to schedule a 2 hour window in case it takes longer than we anticipate.
I apologize for the short notice on this as we need to take action to prevent further unplanned or unexpected downtime.
If you have any questions about this maintenance or the maintenance window feel free to reply here or to open a ticket with technical support.
