This means that you will not be able to log in for a period of about 45 minutes, for sure. The whole server might disconnect at this time as well.Howdy, DreamHoster!
We wanted to let you know we are planning a proactive network maintenance on February 8, 2017 at 10:30pm PST in order to further improve network reliability. This has a planned maintenance window of four hours, and will result in server unavailability of up to 45 minutes.
Once the maintenance has begun, please avoid adding or modifying databases on your MySQL server, as we will be unable to process any database-related changes during this time (and those changes may be lost).
This will only affect availability of your web servers and MySQL servers during the maintenance period -- your email will not be affected.
If you'd like to know more about this maintenance, and view please visit https://www.dreamhoststatus.com for further information and updates.
We apologize for the inconvenience, and appreciate your understanding.
In addition, the server itself may not be very stable (at this point, it really isn't, but regardless...), and it's very likely that any changes that happen within this 4 hour period may be lost. This means your exp, appearance, skills, etc.
