Hi Pondus,
It is also blocked by uBlock filter for me - but server is not down.
HTTP/1.1 403 Forbidden
Server: nginx/1.7.6

Content-Type: text/html; charset=gb2312
Content-Length: 168

<html>
<head><title>403 Forbidden</title></head>
<body bgcolor="white">
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx/1.7.6</center>
</body>
</html>
No Allow or Public header in OPTIONS response (status code 403)
This means there is no default document set, like for instance index.html.
Here you get:

X-Squid-Error: ERR_ACCESS_DENIED 0
X-Cache: MISS from pconline-dl-ngx1-vm238-153.pconline.ctc
X-Cache-Lookup: NONE from pconline-dl-ngx1-vm238-153.pconline.ctc:80
Via: 1.0 pconline-dl-ngx1-vm238-153.pconline.ctc:80 (squid/2.6.STABLE20)
So in fact it could be considered as down.
