to the Enterprise Integration Hub (EIH) database servers for 
the Williams’ Gas Measurement System. We have chosen non-peak 
hours to perform this update to help reduce the impact:

Friday, June 14, 2024, from 10 pm - Saturday, June 15, 
2024, 6 am CST 

The database will be unavailable for downstream systems to 
access and read during the outage. Customers will experience 
delays in some hourly, daily, or gas quality measurement 
reporting. At the conclusion of the upgrade, it is expected all 
missing data will be caught up and available within a few 
hours. 

We apologize for any inconvenience this may cause you. If you 
have any questions or need assistance, please contact your 
Commercial Services Representative or the hotline at 713-215-
