UPDATE:
The issue was in fact a Verizon "routing" issue. I reached out to Verizon and was given the go around, so I contacted my host who did some testing. We used Nord VPN to mask the traffic and performance instantly improved. We still working on trying to get Verizon to do something at a snails pace, but found a work around for the users affected who wanted to stay Verizon. A majority of users just switched to AT&T or another carrier.
----------------------------------------------------------------I'm having an interesting issue that I haven't experienced before. I have a small app that uses only small amounts of data. A couple clients contacted me saying that their users were experiencing slow downs that progressed all the way to the website not responding after all after about 10 minutes of use on their mobile phones.
I couldn't reproduce the issue, and contacted over a hundred other clients and could not find anyone else with the same issue.
After back and forth with them I determined that the issue affects all phone from older and newer android to older and newer iPhones. After about a week of this happening, and being unable to determine or even produce an issue a customer stated they hate Verizon because alot of their sites do the same thing. I contacted each site experiencing the issue... All of them are Verizon.
I contacted many of the customers without issue, and all are on ATT or Us Cellular or Spectrum. None were on Verizon.
Is this possible? Could Verizon be throttling my website or doing something that other carriers are not? I instructed my customers to buy a cheap at&t go phone and try it, and it works flawlessly.
If Verizon is doing this, how do I avoid it? We are a safety app for daycares...so it is very surprising that we would be throttled or limited, but they may not know and it could be some automated system...Or do you think I am completely off base and it is something else?
