```diff
+ Customers on impacted Salesforce Core instances are still experiencing slower-than-normal page load times. We're investigating a possible link to the large number of customer orgs that moved between instances over the weekend, and we're confirming which instances were impacted. We're also reviewing two recent changes common to some impacted instances and evaluating ways to spread the load more evenly across our systems.   We'll share our next update in 30 minutes, or sooner if we have more information.
