## Data quality

- The exact-site identity is strongly supported by the TDLR record: project EABPRJB0802199, CISCO SYSTEMS DATA CENTER, 2260 Chelsea Blvd., Allen, Texas, owned by Cisco Systems Inc.
- The TDLR record describes a 162,000-square-foot private data-center construction project completed in 2010 and marks the project record closed; that administrative status should not be interpreted as proof that the operating facility is closed.
- The Cisco blog sources are operator-authored and provide facility information but are not independent community-impact reporting. The Comptroller record also contains administrative data-quality limitations, including an anomalous zone-created date and several 'No Response' fields.
- No evidence located in the reviewed corpus supports attributing Red Oak, TierPoint, CyrusOne, or other Allen-area data-center activity to this Cisco facility.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
