Performance degradation: USA1132, USA1212, USA1222 (+9 more)
Resolved after 1 hour 47 minutes, affecting USA1132 and USA1212 and 1 more, on November 10, 2026.
We resolved the slow page load times affecting the impacted instances. A rebalancing of our caching system slowed page load times. We stopped the rebalancing and moved traffic to a different part of our caching system. Page load times returned to normal and have remained stable. We apologize for how this incident may have affected our customers and their businesses. We'll investigate further to confirm the trigger and underlying cause, and to prevent this from happening again.
