看到 arXiv 宣佈上了 Fastly 的 CDN：「Faster arXiv with Fastly」。

翻了一下 arxiv.org 的 DNS record，可以看到現在是這樣：

;; ANSWER SECTION:
arxiv.org.              10      IN      A       151.101.131.42
arxiv.org.              10      IN      A       151.101.3.42
arxiv.org.              10      IN      A       151.101.67.42
arxiv.org.              10      IN      A       151.101.195.42

用 mtr 測試，看起來 HiNet 過去的 routing 還是進到新加坡。

不過 static.arxiv.org 是在 CloudFront 上：

;; ANSWER SECTION:
static.arxiv.org.       3600    IN      CNAME   daa2ks08y5ls.cloudfront.net.
daa2ks08y5ls.cloudfront.net. 60 IN      A       13.35.35.100
daa2ks08y5ls.cloudfront.net. 60 IN      A       13.35.35.29
daa2ks08y5ls.cloudfront.net. 60 IN      A       13.35.35.88
daa2ks08y5ls.cloudfront.net. 60 IN      A       13.35.35.127

依照官方的說明看起來還在換，只是不知道已經在 CloudFront 上的 (像是上面提到的 static.arxiv.org) 會不會換過去：

That includes our home page, listings, abstracts, and papers — both PDF and HTML (more on that soon).
