PTA blocking some Facebook CDN servers


#1

I am surprised that no one else noticed or mentioned that PTA has now blocked some Facebook CDN servers. The one I noticed (When I couldn't load some pictures) is http://a3.sphotos.ak.fbcdn.net . I am using Wateen at the moment, and I got

I have sent a complaint to PTA, and I request other people affected by such pointless bans to do the same.

I am also facing such messages some times. I thought that it is by Facebook, But as you said it is by PTA, ????

@Asad & Ayub:

Which ISP are you guys using? You are getting the one of the two normal responses from Facebook itself per my best guess (the other being redirected to Facebook homepage), and not being blocked by PTA. Unlike Imran and my ISP which apparently is blocking this server. I am getting that message after it redirects to

"http://10.16.6.41/redirect.php?n=10.194.142.133@Isb-wisal-plaza&s=124"

P.S: Which ISP are you using Imran?. This block might only be just on Wateen. And it seems that all of the http://a*.sphotos.ak.fbcdn.net subdomain is blocked.

Update: Sent a complaint to Wateen too, and talked to their Online support (Which surprisingly for a Pakistani company, was available). The CSR said they will contact their "Network team" about this and update me back.

I'm getting

Access Denied

You don't have permission to access "http://a3.sphotos.ak.fbcdn.net/" on this server.

Reference #18.676ed540.1296811097.eb3391

But I'm getting the same message when I try to access that link from a server in US as well (accessing via RDP).

^ Yes that is the normal error you should get when trying to directly access a CDN server of Facebook (or you should get redirected to Facebook homepage if you are following an exact link which has its privacy settings restricting public access).

If it is being blocked by an ISP or PTA, you would get an error like:


#10

I see...well I checked on PTCL and Nayatel and they both were showing the 'Access Denied' message; so I guess its a Wateen issue.

Maybe they are just redirecting to that page when they see a 403 status code?

I don’t think so. I can see the “Access denied” error on “http://sphotos.ak.fbcdn.net/” and not the PTA message or redirect


#12

Their network guys seem to be quick, because the block is gone as of now. I see the "Access Denied" page on all a*.sphotos.ak.fbcdn.net links, and can see the all the images in Facebook as well. Though I am really curious to know why this happened in the first place...


#13

i think it is measure against "hot linking" if you refer that URL within the context of FB Site u will not get this error


#14

what does this site links to? by the way
