Interesting Ali Express web server behavior...

So I’m having trouble connecting to the Ali Express web server this evening and decided to investigate a little. What I found surprised me… owen@odmbpro3-3 ~ % openssl s_client -connect www.aliexpress.com:443 CONNECTED(00000005) depth=2 C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global Root CA verify return:1 depth=1 C = US, O = DigiCert Inc, CN = DigiCert TLS RSA SHA256 2020 CA1 verify return:1 depth=0 C = CN, ST = \E6\B5\99\E6\B1\9F\E7\9C\81, L = \E6\9D\AD\E5\B7\9E\E5\B8\82, O = Alibaba Cloud Computing Ltd., CN = ae01.alicdn.com verify return:1 … certificate stuff, blah blah from Akamai, routine… SSL-Session: Protocol : TLSv1.3 Cipher : AEAD-CHACHA20-POLY1305-SHA256 Session-ID: Session-ID-ctx: Master-Key: Start Time: 1702187128 Timeout : 7200 (sec) Verify return code: 0 (ok) --- read R BLOCK read R BLOCK GET / HTTP/1.1 Host: www.aliexpress.com HTTP/1.1 302 Moved Temporarily Content-Type: text/html Content-Length: 258 Location: http://33.3.37.57/ Access-Control-Allow-Origin: https://hz.aliexpress.com Server: Tengine/Aserver EagleEye-TraceId: 2103253917021871367418570ec8e3 Strict-Transport-Security: max-age=31536000 Timing-Allow-Origin: * Date: Sun, 10 Dec 2023 05:45:36 GMT Connection: keep-alive Set-Cookie: ali_apache_id=33.3.37.57.1702187136742.612980.2; path=/; domain=.aliexpress.com; expires=Wed, 30-Nov-2084 01:01:01 GMT Server-Timing: cdn-cache; desc=MISS Server-Timing: edge; dur=65 Server-Timing: origin; dur=3 Server-Timing: ak_p; desc="1702187128314_400069768_2521981097_6837_5323_25_43_-";dur=1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html> <head><title>302 Found</title></head> <body bgcolor="white"> <h1>302 Found</h1> <p>The requested resource resides temporarily under a different URI.</p> <hr/>Powered by Tengine</body> </html> … OK, so far so good, though the hard coded IP redirect is a bit odd.

Is this legitimate? Ali hoping to get away with squatting, or something else? Owen

Outside plant - prewire customer demarc preference
by Sean Donelan 09 Dec '23

09 Dec '23

Of course, every local carrier will be different, what are the current preferences for pre-wiring a customer demarc (NID, the box that hangs on the outside of the house, whatever the service provider calls it now)? 1. Nothing - telco/cable will do whatever the heck they want and wreck the outside of the house anyway 2. Smurf tube from demarc to central distribution point with an interior power outlet near the demarc 3. ANSI TIA-570 prewire (2 x CAT 6, 2 x RG 6) from demarc to central distribution point (low-voltage contractors don't use UV-rated cable for the demarc, and the jacket is trash in a few years) In the past, I found if I made the pre-wire look nice and easy for the field technician, they usually made the extra effort to keep their work clean and tidy.

For those of you who list your network (usually wireline, but sometimes wireless) with third parties, are you supplying just the KMZ or lit buildings as well? If lit buildings, are you including residential? How are you defining near-net? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

The rise and fall of the 90's telecom bubble
by Dave Taht 06 Dec '23

06 Dec '23

Aside from me pinning the start of the bubble closer to 1992 when commercial activity was allowed, and M&A for ISPs at insane valuations per subscriber by 1995 (I had co-founded an ISP in 93, but try as I might I cannot remember if it peaked at 50 or 60x1 by 1996 (?) and crashed by 97 (?)), this was a whacking good read, seems accurate, and moves to comparing it across that to the present day AI bubble. https://www.fabricatedknowledge.com/p/lessons-from-history-the-rise-and In the end we sold (my ISP, founded 93) icanect for 3 cents on the dollar in 99, and I lost my shirt (not for the first time) on it, only to move into embedded Linux (Montavista) after the enormous pop redhat's IPO had had in 99. The company I was part of slightly prior (Mediaplex) went public December 12, 1999 and cracked 100/share, only to crash by march, 2000 to half the IPO price (around $7 as I recall), wiping out everyone that had not vested yet. I lost my shirt again on that and Montavista too and decided I would avoid VCs henceforth. I am always interested in anecdotal reports of personal events in this increasingly murky past, and in trying to fact check the above link. So much fiber got laid by 2000 that it is often claimed that it was at least a decade before it was used up, (the article says only 2.7% was in use by 2002) and I have always wondered how much dark, broken, inaccessible fiber remains that nobody knows where it even is anymore due to many lost databases. I hear horror stories... The article also focuses solely on the us sector, and I am wondering what it looked like worldwide. I believed in the 90s we were seeing major productivity gains. The present expansion of the internet in my mind should not be much associated with "productivity gains", as, imho, reducing the general population to two thumbs and a 4 inch screen strikes me as an enormous step backwards.

Any comprehensive listing of where Google's IPs originate from?
by Drew Weaver 06 Dec '23

06 Dec '23

Hello, We are trying to reduce latency to a region in Google Cloud which we are in the same city of. Latency is currently about 22ms rt for the traffic to go 9 miles. I am having the hardest time finding any comprehensive list of what exchanges, transit, etc their IP addresses are being announced over. Specifically trying to get closer to addresses in these prefixes: 34.162.192.0/18 34.162.64.0/18 Any info is greatly appreciated. Thanks, -Drew

Fiber/OSP Technician Training and Apprenticeship Programs
by Rhys Barrie 05 Dec '23

05 Dec '23

Hey all, I've recently been working with our county's broadband task force, investigating the expansion and equity of broadband networks on a local and state level. Through that, it's become clear that there's a painful shortage of fiber / outside plant technicians in the state of Michigan (if not nation-wide) in order to fulfill the workforce requirements of maintaining the current broadband fiber infrastructure in the state, much less to fuel fiber expansion, and especially in rural areas. There appear to be few options for training the required workforce, especially outside of the large enterprises that have the resources to run their own internal programs, and small (or even mid-sized) ISPs seem to be left with predominantly informal person-to-person transfer of internal knowledge, assuming that they have the required internal knowledge in the first place. This need for a qualified workforce is exacerbated in the face of the multitude of state and federal programs to encourage broadband internet expansion and equity, such as the upcoming $42.5 billion in BEAD grant funding and corresponding construction starting in ~12-18 months state- and nation-wide. As a result, our workforce development team over here at Mott Community College (Genesee County, MI) is working to develop a fiber / outside plant training and apprenticeship program in order to help address this shortage of qualified personnel and training options at a local and state level. We're looking for some industry contacts that would be interested in collaborating with us to establish high-level requirements regarding what skills need to be taught to prospective fiber / outside plant technicians, what qualifications trainees should have after completion in order to fulfill current workforce demands, and to otherwise provide input in sketching out a high-level curriculum. We're looking for feedback from a wide cross-section of industry stakeholders -- large enterprise backbone transit providers, rural residential ISPs, fiber co-ops and municipal networks, operations and outside plant managers, etc. -- in order to determine what the industry wants and needs, and how the entire community college system can help meet those needs. If anyone thinks that they have valuable input to provide regarding these workforce requirements, or knows the right people to talk to, please reach out and let me know!
