Testing for Fermilab phone system-Incoming calls on Aug. 5

Due to the recent issue with incoming phone calls not working onsite, AT&T and the lab will be conducting testing on Friday, Aug. 5 between 1 and 2 p.m. During this time, there may be brief periods during which any active calls from offsite to onsite phones will be disconnected. 

If there is an emergency during this time, call x3131 from an onsite office phone; if calling from outside the lab or on a personal cell, dial 630-840-3131. If you need to reach the Fire Department by cell, you can call Fire Chief Steve Hernandez at 224-230-3701.
