探测信号，就好比你一个人在空旷的天地中，对着四面大喊，有人吗！！！！

找到英文版核实了一下，最后的帖子确实有内容：
Date: 0.412 Msec since loss of contacts
Text of message:
I have still not recovered contact with any network site known to be spinward of me.
Apparently, I am right at the edge of a catastrophe.
If you receive this ping, please respond! Am I in danger?
For your information, I have no trouble reaching sites that are antispinward. I understand an effort is being made to hop messages the long way around the galaxy. At least that would give us an idea how big the loss is. Nothing has come back as yet -- not surprising, I guess, considering the great number of hops and the expense.
In the meantime, I am sending out pings such as this. I am expending enormous
resources to do this, let me tell you -- but it is that important. I've beamed direct at all the hub sites that are in range to the spinward of me. No replies.
More ominous: I have tried to transmit "over the top", that is by using known sites in the Transcend that are above the catastrophe. Most such would not normally respond, Powers being what they are. But I received no replies. A silence like the Depths is there.
It appears that a portion of the Transcend itself has been engulfed.
Again: If you receive this message, please respond!

暗示瘟疫已经便当？

也许意味着瘟疫已经控制了超限界的一部分了。

不是啊，书中明说的是超限界的一部分被淹没了，变成了爬行界，因此超光速通讯中断了，帖子只能以光速通信，当然就没有回音
