<content type="html" xml:base="https://blog.rust-lang.org/inside-rust/2023/01/24/content-delivery-networks.html">&lt;p&gt;Over the past few weeks, the &lt;a href&#x3D;&quot;https://www.rust-lang.org/governance/teams/infra&quot;&gt;Infrastructure Team&lt;/a&gt; has been working on setting

up a second &lt;a href&#x3D;&quot;https://en.wikipedia.org/wiki/Content_delivery_network&quot;&gt;Content Delivery Network&lt;/a&gt; (CDN) for releases and crates.&lt;/p&gt;

&lt;h2&gt;&lt;a href&#x3D;&quot;#what-is-changing&quot; aria-hidden&#x3D;&quot;true&quot; class&#x3D;&quot;anchor&quot; id&#x3D;&quot;what-is-changing&quot;&gt;&lt;/a&gt;What is changing&lt;/h2&gt;

&lt;p&gt;Rust releases (&lt;code&gt;static.rust-lang.org&lt;/code&gt;) and crates (&lt;code&gt;static.crates.io&lt;/code&gt;) will be

served through both &lt;a href&#x3D;&quot;https://aws.amazon.com/cloudfront/&quot;&gt;AWS CloudFront&lt;/a&gt; and

&lt;a href&#x3D;&quot;https://www.fastly.com&quot;&gt;Fastly&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;This is a transparent change to the infrastructure that doesn&#x27;t require users or

developers to take any action. We expect no downtime for Rust users as part of

the migration.&lt;/p&gt;

&lt;p&gt;This also covers only the CDNs for releases (&lt;code&gt;static.rust-lang.org&lt;/code&gt;) and

crates.io (&lt;code&gt;static.crates.io&lt;/code&gt;), no changes are planned for the rest of Rust&#x27;s

domains.&lt;/p&gt;

&lt;h2&gt;&lt;a href&#x3D;&quot;#timeline&quot; aria-hidden&#x3D;&quot;true&quot; class&#x3D;&quot;anchor&quot; id&#x3D;&quot;timeline&quot;&gt;&lt;/a&gt;Timeline&lt;/h2&gt;

&lt;p&gt;We are starting the rollout of the new CDN tomorrow, on January 25th, with

&lt;code&gt;static.crates.io&lt;/code&gt;.&lt;/p&gt;

&lt;p&gt;The rollout will happen very gradually over a period of time. We will start to

send a small percentage of traffic through &lt;a href&#x3D;&quot;https://www.fastly.com/&quot;&gt;Fastly&lt;/a&gt;,

while observing the performance and reliability of the new network. As we gain

confidence, we will slowly increase the amount of traffic.&lt;/p&gt;

&lt;p&gt;Once &lt;code&gt;static.crates.io&lt;/code&gt; has been deployed, we will start working on

&lt;code&gt;static.rust-lang.org&lt;/code&gt;.&lt;/p&gt;

&lt;h2&gt;&lt;a href&#x3D;&quot;#report-issues&quot; aria-hidden&#x3D;&quot;true&quot; class&#x3D;&quot;anchor&quot; id&#x3D;&quot;report-issues&quot;&gt;&lt;/a&gt;Report issues&lt;/h2&gt;

&lt;p&gt;If something &lt;em&gt;does&lt;/em&gt; break, please let the &lt;a href&#x3D;&quot;https://www.rust-lang.org/governance/teams/infra&quot;&gt;Infrastructure Team&lt;/a&gt; know on

&lt;a href&#x3D;&quot;https://rust-lang.zulipchat.com/#narrow/stream/t-infra&quot;&gt;#t-infra on Zulip&lt;/a&gt;.&lt;/p&gt;
