Forced to add a Mobile broadband line, forming a dual-egress with Telecom broadband
Last week, the Telecom technician came to my door again, saying they suspected I had PCDN at home. The basis for suspicion was a large amount of upstream and downstream traffic for 215 consecutive hours (actually, I downloaded very little during this period, less than 1T of downloads in 215 hours, and upload was not even 300G~). I was speechless. My Transmission upload limit is already set to 1024 KB/s, what else do they want me to do?
Just looking at the recent online cases of users being speed-limited or disconnected by operators under the guise of PCDN, it feels like major operators are using PCDN as a catch-all excuse to crack down heavily on users with large upload volumes (this ”large” is relative to average home users; you know, an average home user's upload might not even exceed 1G a day~) so I also felt the danger: after all, I am an old user using a public IP package at a very low price, which makes me a thorn in Telecom's side. If they catch an opportunity to claim I violated the rules and take back my public IP, it would be a huge loss (although I don't really need a public IP right now, but not taking advantage of a good deal is just foolish).
After thinking it over, and combined with the experience of being disconnected by Telecom for 3 days last year, I already had a sense of crisis. So I simply got another Mobile gigabit broadband line, claiming 1000 Mbps downstream and 100 Mbps upstream.

Believe it or not, there really is nearly 130 Mbps upstream:

After more than a week of tinkering, I completed the traffic splitting for the intranet terminals. Terminals related to the home data center go through Telecom, while other applications (including PT downloading) go through Mobile. The Mobile egress is set as my home's default egress, while the Telecom and Mobile egresses serve as backup lines for each other. Now, except for power outages, I no longer worry about access issues for some applications due to broadband problems. Although it was a forced addition of Mobile broadband, I suddenly feel that dual broadband indeed brings a greater sense of security. At the same time, it can be considered as fulfilling my long-held wish for dual broadband~~~.

1 Background Introduction The fundamental trigger that initially gave rise to the idea of setting up a WordPress multi-active solution was actually very simple: that time my home was disconnected by Telecom for a full 3 days without any warning (see article for details: Home Data Center Series: Talking about Current Personal Blogs from This Home Disconnection...
1 Preface Since my blog adopts a special WordPress active-active architecture (the Mac mini in the home data center is the primary-write/secondary-read node, and the Chicago Racknerd VPS is the primary-read node), once there is a content change on the Mac mini node (all blogs...
1 Preface In the previous article (see: Home Data Center Series: Transforming a Retired Mini PC with X-WRT: An Alternative Choice for Main Router), I used an idle J2900 x86 mini PC to tinker with a software router. It ran fine, with performance to spare and a stable system...
Warmly Celebrating the Term ”Home Data Center” Temporarily Ranking First in Google Search Results
It wasn't easy. In the Google search results for the term ”home data center”, ”Baidu Baike” and ”Wikipedia”, which had long suppressed me, were finally overtaken by me once. Although this moment will certainly be brief, it is still worth posting a status update about:
1 Preface The main router of my home data center has always been iKuai. Its main advantage is supporting multi-dialing (for the detailed concept of multi-dialing, see the article: ). Since my home Telecom broadband supports up to 3 dials, I can obtain 3 public IPv4 addresses simultaneously, which for someone like me with multi-line access...
1 Preface When deploying a WordPress multi-active node solution, a crucial technical point is read-write separation: that is, routing all operations involving "writing to the database" (such as publishing articles, modifying content, modifying plugin configurations, submitting comments, etc.) to the primary-write node, while other nodes...
1 Preface I have always wanted to build a synchronously updated static copy for my WordPress-based dynamic blog. On one hand, it is out of the pursuit of "full-site caching" and "always online" capabilities—after all, in the early days, the blog had not implemented disaster recovery and active-active deployment, and WordPress itself...
