UPDATE: These maintenance windows are now complete.
Starting tonight we will be performing a series of partition resizes on our file servers that will allow us to streamline our backup process. Each file server is broken up into 16 partitions and we will be doing the resizes on one partition at a time. Each resize is estimated to take about 20 minutes to complete during which time that partition and all repositories stored there will not be available. During the resize of your partition you will see a notice on the website informing you of the temporary unavailability and you will not be able to push, pull, or clone your repos via Git.
Thanks for your patience as we improve this portion of our infrastructure.
