这个是帮助台邮箱,可以把问题发过去
例:http://edu-k.youku.com/crossdomain.xml 打不开
另外,以下IP段应该经过长宽出口,实际上却没有:

58.66.0.0/15
124.172.0.0/15
124.193.0.0/16
115.182.0.0/20

我们老师说10.8这两个dns的话和一些下载是走长城带宽加速出口的。但不知道你的问题是不是这个
哈哈,看到你comment。。。

@LamJet
学校默认的DNS根本没有做什么特殊处理,纯粹是转发和缓存运营商(移动、联通)的DNS

LamJet avatar LamJet commented on August 15, 2024

虽然学校的dns确实很渣吧,但加速出口是有的好像。。。(我有理解错么?还是说连加速出口都是运营商的?

@LamJet
所谓加速是通过设置静态路由将部分IP段转发到长宽实现的,在不按域名分区解析的情况下,效果 十分有限 ,你觉得用移动、联通的DNS能解析到长宽的CDN么?

额,我还是说明一下,虽然我是网络中心的,但我并没有权限了解到学校对于ip屏蔽的事情。我只是尽我能力把能了解到的可以告诉你,但是我还是一个小白,不太懂这些事。。。

@LGA1150
分区是指分地区么?不能吧。之前只知道老师说优酷好像出了点问题,恰好看到这个评论,就问了一下老师,老师说现在已经算弄好了。。。。。。但至于为什么会屏蔽教育网,(能贴图么?)老师是说可能教育网还有缺陷什么的。最好还是发邮件到南校吧,或者我也可以帮你们下单,在不违反纪律的前提下,我可以帮你们关注后续。。。

@LamJet
配置静态路由的操作十分简单,我还在Windows下配置过;

“教育网还有缺陷”这是把锅强行甩给教育网了,这两段IP之前就正常地走教育网出口,速度20Mbps,现在出现这种情况显然是人为的

@LGA1150 那还是下单问南校的人吧。如果只是东校的问题我在跟这边的老师说,不过工单的话应该都是会得到回复的

@LamJet
针对教育网和长宽的静态路由在所有校区都一样

from sysuv6-dns.

LamJet avatar LamJet commented on August 15, 2024

额,我的意思是因为其实差不多所有事情都是归南校管的,东校能干的还是很少。发帮助台邮箱也是南校处理的,所以我的本来的意思就是发帮助台邮箱质问一下他们吧。(嗯,我在这里也是跳到长城带宽

LGA1150 avatar LGA1150 commented on August 15, 2024

刚才用长城家庭宽带测试同IP段,排除是长宽屏蔽的可能性

@LGA1150
好像现在校园网连优酷的网页都无法打开了,追踪路径的时候,优酷的教育网节点好像又多了一跳,跳到本地的交换机去了?不知道这是什么问题。。。。

几天前给帮助台发了邮件,打电话来确认了,现在已经修复。
