Scheduled Service Change: Replace CPU fan in limestone1
won't be able to send email during the downtime.
There is no workaround for this issue
Replace CPU fan on limestone1. Limestone1 still services some of the use of the APPSMTP service. If users coded their application to use the IP address they will be affected by this down. If they coded their application to use appsmtp.mail.cornell.edu they will be not be affected.
