Our current ETA for the completion of rebuilding/verifying the RAID disk array is 2-4 hours. There is a possibility of further downtime once that rebuild is done, if server build technicians determine that a physical disk needs to be replaced.
In many cases, moving your production site(s) to another server may be the faster option for getting back online. Please contact support, and we will do our best to assist. We also have a guide for doing this here: https://support.modx.com/hc/en-us/articles/220259027
We apologize, as prolonged downtime events such as this are obviously distressing and inconvenient for you and for your clients and users. We take uptime very seriously and will be learning from this incident so that we will do better in the future.
