Unplanned: PECO Disruption on June 17, 2019

On Monday, June 17, 2019, several Penn buildings momentarily lost network connectivity. PECO accidentally dropped a line on the street, which caused a temporary power disruption to 3535, 3600, 3701, 3624 Market Street buildings. 

This disruption appears to have been a power blip; however, ISC is still investigating this issue. All networking equipment is back up and running at the affected locations. 

We apologize for any inconvenience this may have caused. If you experience any problems that may be related to this power outage, please contact ISC Client Care online at, by email at, or by phone at 215-898-1000.
