No doubt higher upload speed is better and I have raised this issue with CC and via email as well.
However, 10Mbps is not too bad. Some things you mentioned like Google contacts, diagnostics and telemetry don’t consume much data at all.
Google Photos updates only a few new photos taken recently and it happens in the background. We are talking about 20Mb to 100Mb upload for say the new 10 to 30 pictures taken each day. This only takes a couple of minutes and there won’t be any major benefit if it took 90 seconds or 30. Most of the time Google is slow on this anyway. Same applies for cloud backup. There are only a few users, perhaps 2% if even that who would be buying extra storage from Google or Apple and then using it to store large files regularly. Total landline broadband penetration in India is not even 3% of the households. This limiting of upload is necessary due to GPON limitations and is quite common even in the US. Take a look at any US provider except Google and you will see much less upload speed provided except in the highest tier plans which are sometimes symmetrical.Jio could do this too and provide symmetrical speeds from diamond plan onwards.

10 Mbps is too slow for modern usage. There's more to what I just mentioned. Especially with multiple users.

Also, why are you comparing the US with India? @vignesh_venkatesan has clarified.

GPON is truly the future-proof way to go about Fibre Optics for the consumer space.

Going back to the topic, the culprit is cloudfront queries. They are not resolving.

I was talking about Gpon.
Gpon has upload limitations compared to download. A normal gpon has approx 2.5Gbps download ability and 1.2Gbps upload. So right off the bat, you can only provide 50% upload. You can get away with providing symmetrical upload as most users download more but Jio is planning for a large nationwide network. Then we come to time division multiple access (TDMA burst mode) on the ONT at the exchange level. One fiber has to handle all traffic to multiple ONU CPEs so each CPE (home terminal/ Jio router) is given a time slot of a few milliseconds to transmit . All data downstream is received by all ONUs but they ignore everything not coded for them. So you will see how providing higher upload speed would cause more strain on the system. I don’t know if Jio is using 10-gpon but even if they are, it provides a little under 10Gb down and 2.4 up making it even more necessary to limit upload speeds as you have just 25% upload capacity.

Coming to multiple users, it is unlikely more than one person would be on a video call at the same time. If a household has such requirement then they can go for the gold plan where by paying an extra Rs300 they get 25Mbps upload. Yes, I would prefer symmetrical uploads but in real life, I have never felt hampered by the 10Mbps upload speed.

Agreed.
Jio seems to have deployed a more centralised network than the other players.
But the shared between is between the single port right ? Even if they have high split ratio it shouldn't matter much right?
GPON has 2.5gbps down and 1.5 Gbps up per port.

If BSNL can give symmetrical bandwidth on 100 Mbps plan using GPON in a small place like Shillong:

How come Jio with all that political clout is unable to do so? #AmbaniLogic


It seems like symmetrical GPON or rather XGS-PON is possible since around 2010?

XG-PON or XGS-PON: don’t make a costly spelling mistake | Nokia

We love our acronyms in telecoms. TDM, WDM or TWDM. 3G, 4G and 5G. FTT B, C, H, P and X. Acronyms are our insiders’ language and let’s be honest: sometimes they make things more rather than less confusing. I feel strongly that it’s our industry duty to demystify them, rather than leverage the...

There's also 40G since 2013: G.989.1 : 40-Gigabit-capable passive optical networks (NG-PON2): General requirements

So #AmbaniLogic it is. He's got billions of dollars. Implementing a truly symmetrical Fibre backhaul is easy task for him.

Also they have transferred most of the fiber assets from reliance industries to jio. I believe now they have 2nd largest fiber assets in the country after bsnl. And I believe bsnl and jio have same infrastructure for ftth isn't it or not?
