CHAIRWOMAN'S REMARKS - CHAIR YOO
Chair Yoo offered several remarks. First, she advised the AI Workshop, which is part of the
Municipal Technology Roundtable, will be meeting on August 21, 2024 from 11am until 3pm.
On August 29, 2024, the first Cybersecurity Task Force will be meeting at 10am. Next, she
offered a reminder that cybersecurity through KnowBe4 was due on July 19, 2024, so if anyone
did not yet complete it, please do so as soon as possible. Chair Yoo then wished a happy
birthday to CIO Anthony McPhearson.
Lastly, Chair Yoo offered an update with regard to the CrowdStrike outage on July 19, 2024.
She said despite the severity of the outage, DuPage County and other DuPage County agencies
such as ETSB experienced no significant financial losses and minimal service interruptions. She
said this was due to effective communication and cooperative efforts by the DuPage County IT
department, ETSB, OHSEM, and IT leaders countywide. She thanked Mr. McPhearson, Craig
Dieckman, and Linda Zerwin for their direct collaboration in swiftly mitigating the outage's
impact. She said their coordinated efforts with various departments, elected officials, and other
agencies throughout DuPage County were instrumental. Chair Yoo said the County's IT
department's network and operations teams, the PC technicians, OHSEM, and ETSB responded
promptly to the outage starting at 1:41am on July 19th. She said their diligence throughout the
night and morning ensured all critical systems were restored and hundreds of user inquiries and
escalations were addressed that same morning. She said by approximately 7:00am, 95% of our
critical systems were up and fully accessible, which includes roughly 256 servers. She said most
effected workstations were fixed shortly after being reported to our IT Service Desk. She said
notably, while the 9-1-1 system servers and equipment were effected, they remained operational,
ensuring continuous emergency service availability. Essential services such as Police, Fire,
water, and electricity were fully functional, although some individual computers were impacted.
She said the collaboration has continued with a recent incident after action review, led by Craig
Dieckman, and by the end of this week, a detailed report will be provided by Anthony
McPhearson, in partnership with Craig Dieckman and Linda Zerwin, for presentation to the
Chair, Board Members, and DuPage County leadership. Chair Yoo said this outage highlighted
the importance of robust infrastructure, strong support teams, effective response mechanisms,
and countywide collaboration. She said the swift actions of our IT, public safety, and emergency
