Chicago metrics that matter.
Three things Loop IT has to get right.
Trading & exchange-grade uptime
Proprietary trading firms, market-makers, and Cboe/CME-adjacent shops need sub-second failover and tested redundancy. Two diverse fiber entries, co-location liaison, and a 24/7 trading-desk on-call rotation.
Industrial & manufacturing IT
OT/IT separation, plant-floor Wi-Fi, and engineering CAD workstations for manufacturers across the metro. We have run cabling in 100-year-old plants on the South Side and greenfield Plano-style campuses in the suburbs.

“A polar vortex took out our primary fiber and our previous MSP could not get an engineer to our building for six hours. GR IT had someone on-site in 45 minutes, ran us on the backup link, and rebuilt the redundancy properly the following week. They are also the only firm we have worked with that actually understood how a trading desk fails over. That is the standard now.”
