ArXiv Down for 4 Hours
https:&#x2F;&#x2F;twitter.com&#x2F;arxiv&#x2F;status&#x2F;1192508633092898816<p>Not the first time that it happens, but what&#x27;s new is that there are almost no mirrors around anymore. Last year this worked: https:&#x2F;&#x2F;lanl.arxiv.org&#x2F; . Now? Empty folder.<p>I&#x27;m wondering what has been the reason for the sunsetting of arXiv mirrors. Google seems to hate mirrors to some extent, but how much should arXiv care about it? Traffic can&#x27;t be that bad; even in the heydays of mirrors, no single mirror was all that popular (and the files arXiv serves are rarely &gt;5MB in size). Are universities getting that stingy about their bandwidth?
