Interesting, perhaps its just the way Spectra is announcing these routes? 🤔 Since its clear that some subnets get reverse routed bad, I guess it's something Spectra can fix if they want to. 🤷♂️

They can but they won't on non static ip's for some reason. If you do remember last time it was 320ms plus ping Singapore servers. But they did say they can optimized it but later it somehow camedown to 165 as they changed the routing
Hi
Forward trace: Spectra (India) > Linode (Singapore) seems fine. Return trace: Linode (Singapore) > Spectra (India) seems not optimised as routing via Europe.
These issues happen when a network buys IP transit outside in one direction (Europe) only. Either of the following would have fixed the issue:
Let's see how it goes. Good luck!

These issues happen when a network buys IP transit outside in one direction (Europe) only. Either of the following would have fixed the issue:
- Buy IP transit from the same provider in West as well as East (so in Singapore/HK etc).
- Just don't buy transit but simply peer at an IX and keep routes local so that their announcement in EU stays within EU and doesn't reach Asia. But for that, they need to have a cover prefix. So /24 goes via AS6453 from Europe and /23 is announced to transit in India (which maintains it's own connectivity to East and West).
Let's see how it goes. Good luck!

Thank you @Anurag Bhatia 🙇♂️
A follow up question, how is it working better for some Spectra subnets? Are they using the method you described but only for that specific subnet? When the allocated IP address is from 180.151.118.x, the pings are better as @The_PC_Guy shared earlier -- [help] Spectra Ping / Traceroute results to Singapore | Spectra
Also, it doesn't appear to be just with Linode, looks like anything to/fro Singapore. Even speedtest-sgp1.digitalocean.com showed the same 160+ms pings.

Hi
180.151.118.0/24 is announced to their domestic IP transit provider (AS55410 - Vodafone and AS4755 - Tata Comm). Both Vodafone and Tata have PoPs in Singapore and Europe and maintain routing accordingly. They would simply announce route at both locations and hence networks in Singapore will pick their Singapore announcement, networks in Europe will pick Europe announcement.
That way you don't have a case where it's just being announced in Europe and everyone in World has to send traffic via EU for that pool.

It appears they are correcting the routes and/or announcements.
My pings to DO & Linode Singapore are back to 60-70 ms and I have a 180.151.117.x IP address range (which I had for 1-2 days now). Just couple of hours back it was taking 150+ ms, and in the last hour or so, I had numerous issues with connectivity to certain sites. At first I thought its just Cloudflare endpoints, but it looks like its more Singapore bound traffic which were having issues. Even the 1.1.1.1 DNS resolver was not reachable.
Perhaps Spectra is making the changes @Anurag Bhatia suggested.
While typing this message, I lost connectivity again, this site itself wasn't working (but not full down, just certain sites, can't ping and doesn't leave Spectra network). I guess have to wait till things settle down, Spectra seems to be experimenting things. 😛

Yey I'm away right now but will check as soon as i get back

False alarm, they seem to have reverted the changes, pings are back to 150+ ms! 🙁 Maybe it didn't go as planned.

Oh, is that why all of YOU Broadband traffic outside India is being routed through Vodafone's AS1273 in Marseille, France?

Yeah they have started blocking many new sites and even over https it's blocked (says connection reset by peer or something) 😑😑 I started noticing 2 days or so back. 😥
Maybe that's what they were fixing instead of the pings! Going to try DNS over HTTPS tomorrow just read about it in a post now
