During this time, there may be short network interruptions while network devices are reconfigured. Additionally, there may be short outages of the MIS file server (P: drive) while the OS is updated. Also, the central file server will be upgraded, and this may cause a couple of short outages of the J, K, L and M drives. The Zimbra mail servers will suffer a short outage while they are rebooted to finalize patches and install updated certificates. Also, all of the MIS apps will be down while underlying systems are patched and rebooted. All services will be back up no later than 10 p.m. Finally, Windows and Linux patches will be released to CUE-managed desktops and servers. There may be short outages overnight while these servers are rebooted to finalize patch installation. Also, plan on rebooting your Windows or Linux desktop no later than Friday, Oct. 21, to finalize patch installation. If you have any questions or concern about these maintenance activities, contact the IT Division Helpdesk at helpdesk@jlab.org or x7155.<br><br><strong>Colloquium: Gravitational Waves and Black Holes</strong><br>If you’ve heard about the recent detection of gravitational waves and wonder what the kerfuffle is about, come hear Vernon Sandberg, Caltech, explain how our understanding of dynamical gravity changed from theoretical to experimentally confirmed in the early hours of Sept. 14, 2015. Sandberg is a Lead Scientist at the Laser Interferometer Gravitational-Wave Observatory (LIGO) Hanford Observatory in Washington. In this colloquium, he will discuss the LIGO project, the physics behind its interferometers, and the first direct detection of gravitational-wave events. The talk is scheduled for 11 a.m. on Oct. 28 in the CEBAF Center auditorium.<br><br><strong>Veterans Day Collage Needs Your Submissions</strong><br>In recognition of Veterans Day, veterans of military service are invited to participate in a collage to be displayed in CEBAF Center on Veterans Day. This will be similar to the one displayed the past two years. If you submitted a photo in the past, no need to re-submit. For more information or to participate, contact Mike Robbins at mrobbins@jlab.org or x7616. Submissions should be made by Oct. 31 and include a photo of yourself in uniform and your full name, branch of service and years of service. If you do not have a digital copy of your photo, employees can bring a picture to CEBAF Center room C222 to be scanned.<br><br>To access the full version of the JLab Weekly Briefs, visit: https://www.jlab.org/news/briefs/latest</div></div></div></body></html>
