    <title>Disruption with Grok Code Fast 1 in Copilot</title>
    <content type="html">&lt;p&gt;&lt;small&gt;Oct &lt;var data-var='date'&gt;20&lt;/var&gt;, &lt;var data-var='time'&gt;16:40&lt;/var&gt; UTC&lt;/small&gt;&lt;br&gt;&lt;strong&gt;Resolved&lt;/strong&gt; - From October 20th at 14:10 UTC until 16:40 UTC, the Copilot service experienced degradation due to an infrastructure issue which impacted the Grok Code Fast 1 model, leading to a spike in errors affecting 30% of users. No other models were impacted. The incident was caused due to an outage with an upstream provider.&lt;/p&gt;&lt;p&gt;&lt;small&gt;Oct &lt;var data-var='date'&gt;20&lt;/var&gt;, &lt;var data-var='time'&gt;16:39&lt;/var&gt; UTC&lt;/small&gt;&lt;br&gt;&lt;strong&gt;Update&lt;/strong&gt; - The issues with our upstream model provider continue to improve, and Grok Code Fast 1 is once again stable in Copilot Chat, VS Code and other Copilot products.&lt;/p&gt;&lt;p&gt;&lt;small&gt;Oct &lt;var data-var='date'&gt;20&lt;/var&gt;, &lt;var data-var='time'&gt;16:07&lt;/var&gt; UTC&lt;/small&gt;&lt;br&gt;&lt;strong&gt;Update&lt;/strong&gt; - We are continuing to work with our provider on resolving the incident with Grok Code Fast 1 which is impacting 6% of users. We’ve been informed they are implementing fixes but users can expect some requests to intermittently fail until all issues are resolved.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;&lt;small&gt;Oct &lt;var data-var='date'&gt;20&lt;/var&gt;, &lt;var data-var='time'&gt;14:47&lt;/var&gt; UTC&lt;/small&gt;&lt;br&gt;&lt;strong&gt;Update&lt;/strong&gt; - We are experiencing degraded availability for the Grok Code Fast 1 model in Copilot Chat, VS Code and other Copilot products. This is due to an issue with an upstream model provider. We are working with them to resolve the issue.&lt;br /&gt;&lt;br /&gt;Other models are available and working as expected.&lt;/p&gt;&lt;p&gt;&lt;small&gt;Oct &lt;var data-var='date'&gt;20&lt;/var&gt;, &lt;var data-var='time'&gt;14:46&lt;/var&gt; UTC&lt;/small&gt;&lt;br&gt;&lt;strong&gt;Investigating&lt;/strong&gt; - We are investigating reports of degraded performance for Copilot&lt;/p&gt;</content>
