[Updated] T-Mobile allegedly loading code from random trackers into customer portal; likely causing F451 Service Unavailable error?
New updates are being added at the bottom of this story…….
Original story (published on May 13, 2021) follows:
Several T-Mobile subscribers are bumping into the F451 Service Unavailable error when trying to access the customer portal, particularly when logging in, and they’re confused as to why.
After all, F451 is a clear reference to Ray Bradbury’s 1953 dystopian novel Fahrenheit 451 – with 451 degrees Fahrenheit as being the temperature at which paper catches fire spontaneously.
Anyone recognize F451: Service Unavailable message? I tried T-Mobile customer service, and they cut a ticket, but had no idea what the message on the T-Mobile site means.
Anyone experience this T Mobile error message that T Mobile can’t solve? F451 : Uh-oh, it looks like we have our wires crossed. Please try again later. I’ve lost PC account access to my T Mobile account for weeks. T Mobile ‘engineers’ have not provided any answer.
But that doesn’t really explain anything. What the error 451 truly stands for is the unavailability of a web resource due to legal reasons.
Such resources are blocked usually due to government censorship. Still, T-Mobile’s customer portal obviously doesn’t come under the umbrella of government censorship, does it?
So what could be the actual reason? As it turns out, it’s that the T-Mobile site is allegedly loading code from the following third-party sites/trackers into their customer portal:
To be clear, each one represents a security risk. If one of these third-parties were compromised, malicious code would be running in the context of your T-mobile session.
It seems that the above sources are all a part of T-Mobile’s new side hustle of selling customer data to third-party advertisers.
What makes this bit shady though is the fact that T-Mobile didn’t technically proclaim about this proceeding and instead chose to reveal it to the world by quietly modifying their ToS.
Nonetheless, it appears that these trackers and 3rd-party advertisers are to be blamed for the F451 Service Unavailable error on the T-Mobile site. As it stands, blocking them somehow ‘breaks’ the website.
The easiest solution for this problem would be to thus disable all ad and tracker blockers. These may either be built-in in browsers like Firefox and Opera or may function through extensions.
However, this workaround doesn’t exactly seem to be a universal miracle solution as there have been a few user reports stating that disabling ad and tracker blockers made no difference.
In such a case your best bet would be to try some other browser to access the customer portal until T-Mobile sorts stuff out at their end.
Update 1 (February 26)
05:38 pm (IST): T-Mobile Help on Twitter suggested to users that they should try loging out of the app and back in if they are getting service unavailable error.
Having that online account app at 100% is huge for being able to manage your account on the go. If you haven’t had the chance, fully log out of the app and log back in. Send us a DM if that doesn’t help, we’d love to take a closer look with you. ^MaxwellDavis (Source)
