Every store ran on a single broadband line; POS and loyalty systems dropped at peak hours. Customer data could not leave the company boundary.

MPLS between plants was costly and slow to scale, cloud ERP/MES performed poorly, and the nightly data sync with the German HQ took more than six hours.

Video meetings, remote tellers and training ran on three systems with a dozen endpoint models; circuits were bought branch by branch and call-quality complaints were high.

A six-person local team covered GxP data rooms, offices nationwide and cloud resources; 11 monitoring tools produced 15,000 alerts a month and HQ needed English reporting and audit evidence.

Moving 40 TB daily datasets from Shanghai to GPU clusters in Singapore and Tokyo took 20+ hours over the internet, and training data had to leave China over an auditable path.

Sorting-centre networks were built region by region; any outage stopped scanners and sorting lines and backed up parcels.

Each province ran its own Wi-Fi with different SSIDs, authentication and security policies; staff could not roam and site faults took two days or more to fix.

Tenant-built networks interfered with each other and common areas had no coverage. Management wanted one guest and tenant Wi-Fi with real-name authentication and tenant isolation.

Network, security, building controls, parking and energy were seven separate systems from different contractors; tenant circuits took two to three weeks to turn up.

Multiple data centres and clouds relied on manual DNS changes for failover (40+ minutes); breaking-news traffic spiked 5–8× alongside DDoS and scraping.
