Nash Burns Saves the Day
好的,我现在需要帮用户总结这篇文章的内容,控制在100字以内,并且不需要特定的开头。首先,我得通读文章,理解发生了什么事情。 文章讲的是新年之后,作者在英国和德国的朋友和同事发现发给他们的邮件被退回了。他们使用的是Google Workspace的textuality.com域名,DNS等服务由本地公司CWH负责。问题出现后,他们尝试了很多方法,比如更新MX记录、调整防火墙设置、使用VPN测试等,但问题依然存在。最终,在技术支持Nash的帮助下解决了问题。 接下来,我需要提取关键点:邮件弹回、涉及的公司(Google和CWH)、尝试的各种解决方法、以及最终的解决结果。同时,要注意字数限制,所以要简洁明了。 可能的总结结构是:新年期间邮件问题出现,涉及Google和CWH的服务调整和多次排查,最终解决。这样既涵盖了主要事件,又控制了字数。 最后检查一下是否符合用户的要求:中文、100字以内、直接描述内容。确保没有遗漏重要信息,并且语言流畅自然。 </think> 新年期间,作者发现来自英国和德国的邮件被退回。问题源于GoogleWorkspace与本地服务商CWH之间的DNS和防火墙设置冲突。经过多次排查和调整,最终由技术支持Nash解决。 2026-3-20 19:0:0 Author: www.tbray.org(查看原文) 阅读量:6 收藏

What happened was, soon after New Year’s, friends and colleagues in the UK and Germany started letting us know that their emails to us were bouncing. Our “textuality.com” family domain is a Google Workspace (or whatever they call it this year) for email and docs and so on. Its Web presence, including DNS, has for many years been handled by a local outfit I’ll call “CWH” for some absurdly low monthly price, and has been trouble-free.

So, what could be wrong? We investigated and discovered that Google was offering a new-and-improved MX-record option, although they emphasized that the old setup should still work. Anyhow, we installed the New Thing and it didn’t help.

So, we filed a ticket with CWH tech support and somebody got back to us pretty quick, saying they’d changed a firewall setting that was blocking connections to Germany. I detect the scent of GDPR, but whatever.
Euro-email: Bounce, bounce.

CWH: Probably an MX-record issue, and we should wait for DNS propagation. Several days passed and bounce, bounce, bounce.
Us: “Not DNS propagation.”
CWH: “Still could be.”

So we VPN’ed to Germany and discovered we couldn’t ping Textuality’s IP address. Smells like a firewall to me. We told CWH that.

CWH: We have made some changes to firewall settings.
EMail: bounce, bounce, bounce.
VPN+Ping: Request timeout, request timeout, request timeout.

CWH: Try traceroute?
VPN+Traceroute: 14 hops, no joy.

CWH: Your VPN settings must be wrong. Here are instructions to use Windows PC VPN correctly.
Us: Thanks but no.

CWH: Your MX records are configured incorrectly.
Us: No, they are correct per Google guidance. We sent an email beginning “Please believe us.”

CWH: It must be DNSSEC. Check to see if your registrar implements DNSSEC.
Us: We are using your DNS servers.

CWH: Perhaps your registrar is broadcasting an old record?
Us: Our registrar doesn’t do DNSSEC.

At this point we consulted a friend who’s an expert on DNS and Email and even DNSSEC. He verified that not only could you not ping Textuality from Germany, you also couldn’t ping CWH or its name servers. Firewall firewall firewall!

CWH: “I did test the site access using a 3rd party application, and it seems to be accessible on all parts.”
Us: Look at the output, it shows we can’t be reached from anywhere in Germany.

Also, for all the remaining messages in the email trail, we prefixed our input with bold face extra-large text reading: Systems located in Germany cannot ping Textuality.com’s IP address, nor can they ping the IP addresses of textuality.com’s designated name servers. This is the problem.

CWH: Let’s try migrating you to a different server; try pinging these hostnames.
VPN+Ping: Nope.

CWH: Are you sure it’s not your VPN settings?
Us: Are you sure it’s not your GDPR settings?
CWH: Raising your issue to Tier 3.

20 hours pass, then we get email from:

Nash Burns! · …who said “This has been fixed.” It was. Nash’s email signature was “Nash(Rajaneesh) B”. What a great name, though. Thanks, Nash.

Am we mad? · Not really. Consumer-facing tech support is hard. None of their suggestions were unreasonable. Doing GDPR correctly is hard. They’ve been just fine for years and were having a bad week. Could we expect better from any of CWH’s local competitors? Probably not.

It wasn’t funny at the time, but looking back, it kind of is.
