Abstract: Dear colleagues, Altgeld Hall will experience a complete network outage on Tuesday, February 23rd, from 5:30AM to 7:30AM CST. During that two hour window significant parts of Altgeld Hall’s wired infrastructure will be upgraded. Please plan accordingly, as the following services will be affected: - E911 services will be unavailable: you will not be able to use Lync phones to call 911 in case of an emergency! - All wired AND wireless connections in Altgeld Hall will be down - Printing in Altgeld Hall will be unavailable - Departmental email delivery will be delayed To assure a quick restoration of services after the upgrade, it is best if everyone shuts down, or at least logs off of, any departmental computer in Altgeld Hall the night before (Monday, February 22nd). We expect that you will all be able to resume work as usual after 7:30AM. Now for the exciting part: this upgrade will assure gigabit speeds for all wired network connections in Altgeld - a 10-fold increase in speed for everyone! Math IT will work closely with Technology Services to assure a smooth upgrade and minimize any post-upgrade issues. If you have any questions or concerns, please let us know at firstname.lastname@example.org.
