Hello,

For the past few months I am unable to access github.io domains, I can access github.com links but github.io won't open for me.

For quick check
I can access GitHub - microsoft/microsoft.github.io: Microsoft on GitHub this site but not the github.io link Microsoft on GitHub

Edit : As someone replied, the above link redirects to microsoft.com (which does not happen to me as it can't resolve github.io links)
Some more links to try / test

None of the above links would open for me.

Is anyone else having this issue?

I have tried Google DNS, Quad9DNS, OpenDNS and the issue still persists.
It's not just my computer as it's happening over WiFi connected devices too.

My router has no settings to ban any IP, so I am not sure what's the problem.
My ping to github.com returns normal but pings to GitHub.io links come back as timed out.

The ms github.io link is redirect to a Microsoft domain... try disable all extensions in your browser or a different browser or incognito mode?

i think its a routing issue

github.io is pinging for me

Can you do a traceroute using tracert github.io ?

I think you should email mtnl. Sometimes these routing issues get fixed on it own. Until then you can use a VPN like CloudFlare WARP if you want.

Thanks for checking.

I thought so too! So ignored for a while but now its getting really annoying.
Yup can access them via VPN but not the best experience as I don't want all my traffic to be always routed through VPN for some domains I need my region to show India.

Alright mailed selfcare@mtnl.net.in about this. Any other email id I should send this too?
If they don't respond in the next few days, mtnl find grievances email and try to contact them.

Not including all the hops for github.com but goes up to 13 and resolves normally.

Thanks for replying. I have attached a screenshot of my ping to the server.
So its not a browser issue for sure.


Ping has nothing to do with browser redirect, in case it is getting blocked in your computer/phone browser... have you tried different browser or disabling all extensions temporarily?

Oh my bad I misread your ping info... I am able to ping github.io so yeah looks like MTNL issue... try contacting them on twitter and raising a ticket on PG portal?

Once on my BSNL fiber dockerhub website was not opening and I contacted them on twitter and it started working after 1-2 days - not sure if they responded to my message or it resolved on its own!

I hoped someone on the forum using MTNL Mumbai could answer that. I guess not many MTNL users here now.

Jio Fiber is being installed in my building and they offering 30 days free trial with STB and stuff. I might get that for 30 days and in the meantime also register a complaint at pgportal.

Any experience with Jio Fiber service?

I am really not a fan of Jio and tbh MTNL has been good to me, no service issues and whenever there is one(once in like 3-4 months), one complaint and its gets resolved in 1-2hrs. But I guess we MTNL users are a dying breed here.

Yep... Jio has frequently issues like this... Websites getting blocked but they usually resolve in couple of days...

Why not take Jio too... And keep one or the other as backup?
