DNS Resolution phone = yes home internet = no ???
It makes no sense how BOTH my iPhone and T-Mobile gateway connect to the SAME 4G and 5G cells yet DNS doesn't resolve over the gateway. I can ping major DNS server IPv4 addresses and get a response on my MacBook Pro and a Linux client but neither can resolve host names. Even the email does not work on my MACBook.
Calling the T-Mobile support line at 7-7:30 am is of no avail. Even a call back tells me they are not able to answer my call. Why bother even calling support as it fails just as bad. I doubt they could answer the question anyway.
It is as if the home internet gateway connection has zero priority. The cellular metrics on both the phone and gateway are good and basic pings do pass so it looks like some configuration screwup impacting traffic from home internet gateways here.
OK so there was some issue with DNS that T-Mobile was having but they seem to have resolved it yet again. Nothing advertised as to what the cause of the behavior was but it works again. Using the workaround to set the client DNS vs allowing the gateway IP works good.
It is clearly related to DNS resolution with traffic from home internet connections. If you can ping the IP address of CloudFlare or Quad9 or Google but not the host name that is a red flag. This doesn't impact my phone at all only the home internet is jacked.
We are in east TN so from a regional standpoint it might be related to the passing of hurricane Ian but we saw no major impact or that here. Since everything works on the phone but not on the home internet it may be something configured wrong for priority. They can't even get their support lines to work. T-Mobile needs to figure out how to send text notifications out to subscribers via their phone when they have regional issues with their internet service.Just a point of reference. Speedtest on a client cannot find the servers. Speedtest on my phone does work and reports 180 mbps download so clearly there is bandwidth but for the n41 results are meh… but to be expected first thing in the a.m. due to load. Since the gateway fails to pass much other than pings I don't know where the load comes from.
I’m having the same issues myself right now, and I can’t get ahold of anyone and I’ll leave a call back request just to get called back saying can’t nobody call me back…i don’t know what to do at this point I can’t connect my phone nor Xbox to the internet for the kids but I can do mobile hot spot?? How do I have service but not internet ??

If you go to downdetector.com you can clearly see a spike in reports of issues starting just after 4 am today. T-Mobile seems to be having some major problems currently. I checked several other ISPs and they had no problems currently reported.
If you load the downdetector mobile application the map shows T-Mobile on the east and west coast with huge red areas. They have major issues currently.
When you zoom in it doesn’t look as bad but clearly issues.
It appears that around 41% of the reports are mobile internet related. Around 28% are mobile phone reports so I guess it could be worse.
Same issue here in middle TN. Looks like it's an issue in TN. T-Mobile support swears there is no issue on their end, but that's clearly wrong.
K town east TN also down
