php issues over att network

Any php files on the website work fine across all browsers, phones etc except on AT&T service the php functions are replaced with semi random characters. As well, a 0 is placed at the bottom of every php page. If we switch the device over to Wifi, problems are gone.

If all include/include_once functions are removed the page works fine.

Also, this doesn't seem to be specific to just Apple devices.

Re: php issues over att network

I'd like to add that this has been tested on other provider's networks and the issue doesn't show up. It seems to be a problem with the AT&T's proxy server.

Re: php issues over att network

I am a developer and just built a large site for a client and we are getting the same results.  It has been happening for about 2 weeks.  Random characters are showing up on the screen and only on AT&T and not when on wifi.

 

This is happening in Texas but up in Raleigh, NC on AT&T it is fine.

Re: php issues over att network

jctek123 - thanx for your reply. I saw this same post over on stackoverflow (which has since been marked as "closed"), but couldn't contact the poster (stack doesn't allow contacts). So I posted it here in the hopes that someone from AT&T would look into it.

 

I am also in Texas, and have confirmed that it is NOT happening in Florida, Alabama or New Mexico.

 

I've heard of this issue happening when using a transparent proxy like "squid", so I can only assume that AT&T made a localized change to the proxy being used in the Texas locations.

 

Can someone from AT&T take a look at this issue?

Re: php issues over att network

My client is about to Call AT&T.  It just happens that of course my client is in Texas where the problem is.  We spent several hours trying to trouble shoot it just to discover that it is a problem with the AT&T network.  Glad someone else has started a thread so someone can try to fix it because I was all tapped out of ideas.  Been doing web deisgn for 15+ years and have never seen this issue before.

jctek123 - did your client call AT&T? If so, was anything...

Re: jctek123 - did your client call AT&T? If so, was anything...

Yep!  After about 3 hours on the phone with several people he finally got a tech on the phone and after going back and forth for a while he finally got the tech to admit that multiple people were having issues and they would look into it.

 

That's all I got for now.

I have also been seeing this for about 1 week in PA/NY. If I use verizon or view the site using secure socket  (https), the extra inserted characters are gone.

In addition, my usb connected wifi device quit working on att network during this time (also strange timing), my new att iPhone hotspot shows the same issue. Scans with clamx have not found found issues on my mac. 

If I share out to another Mac, the issue is present.

 

Has anyone confirmed it being related to dns servers, I am also wondering if they can do it.

Can I have my iPhone use open or google dns?

Thanks for all the input!

Re: php issues over att network

I have the same issue in Kentucky.  Do you have a contact within AT&T to report the issue to?

 

I tethered to my phone from my laptop and got the same results with firefox and chrome.  But, interestingly if I do a wget, the page does not contain the extra characters.

Brad - sorry for the delayed response. I was off the grid for a bit for Labor Day weekend.

 

RE: being related to DNS servers. -- If it is, then it is out of our control and would be something that AT&T controls through their cellular network.

RE: Can I have my iPhone use open or google dns? Yes, but only when you are connected to a WiFi network. You cannot change the DNS lookup for cellular data (see previous point).

 

I have not had any luck with this issue yet, and was hoping that jctek123 had an update from his client.

 

I have tried to call AT&T a couple of times, but I don't have the time to sit on the phone for 2 or 3 hours. When I do get to talk with someone, I either get someone who is clueless, who doesn't care, or both.

 

I am really hoping that jctek can provide an update, or maybe even get us the number that his client called. If we all call the same person, maybe we can start making some headway with this?

 

I am completely at a loss with this, and I feel it is completely in AT&T's hands.

Tiny - thanx for the info with FF and Chrome, and for the confirmation that it is happening in KY.


If anyone on this thread who is seeing this issue comes up with any further info, or even a solution, please do let us all know.

Re: php issues over att network

I agree tbomber,

We are only seeing these extra characters with att. The same server is sending out the sites fine, the files on the server are fine. We have tested multiple browsers and multiple ISPs. This is ONLY with att. I would like to switch DNS, put that is not an option as you noted. I also do hosting and have looked at that end put do not find any issues with files, control system, upgrades and it does not show on any other network. Interesting that https and wget do NOT show it.

 

We do need someone from att with a solid info of the network to look at this. I keep wondering, is it a network virus able insert characters in some situations or maybe a network protection system that is just a little off and causing some slight incertions. 

 

I am also thinking that we should reach out to other forums. I am going to post the question to the plesk forum and link to this, maybe other hosters have seen this? Brad

Re: php issues over att network

Sorry guys, nothing to report on my end.  My customer actually called back and they said they had no record of the orginal call.  SHOCKER!

 

They esclated it back to a higher level tech and they are still looking into it and my client is still waiting to hear back.  Wish I had better news!
