Starting just after 12 pm ET and continuing throughout the day on Monday June 15th. T-Mobile had been experiencing a voice and text issue that intermittently impacted customers in markets across the U.S.
That led to rumors and the news media jumping to conclusions that the largest ever DDOS attack was underway against the United States.
But it wasn’t.
T-Mobile provided some basic information about the root cause….. It was a failure that overwhelmed their network.
The trigger event is known to be a leased fiber circuit failure from a third party provider in the Southeast. This is something that happens on every mobile network, so we’ve worked with our vendors to build redundancy and resiliency to make sure that these types of circuit failures don’t affect customers. This redundancy failed us and resulted in an overload situation that was then compounded by other factors. This overload resulted in an IP traffic storm that spread from the Southeast to create significant capacity issues across the IMS (IP multimedia Subsystem) core network that supports VoLTE calls.
We have worked with our IMS (IP Multimedia Subsystem) and IP vendors to add permanent additional safeguards to prevent this from happening again and we’re continuing to work on determining the cause of the initial overload failure.
So, I want to personally apologize for any inconvenience that we created yesterday and thank you for your patience as we worked through the situation toward resolution.
Be careful what you read and believe in the early reporting about security or computer incidents… The facts may not be what is being reported.
Cyber Roadmap 
You actually make it seem so easy with your presentation but I find this matter to be actually something that I think I would never understand. It seems too complex and very broad for me. I’m looking forward for your next post, I抣l try to get the hang of it!

Hey this is kinda of off topic but I was wondering if blogs use WYSIWYG editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding experience so I wanted to get guidance from someone with experience. Any help would be greatly appreciated!

There are times you have to code. I’ve developed major websites with much raw code. Html php etc. But, very little coding has been required w WordPress so far. Someday I may need to code for a feature or ad , or something where a plugin isnt available. But it’s all gui so far.
