Most hosting providers suspend service a short time after failed payment. I wonder why they've let this go on for 4-5 months, especially with a bill that massive.
I guess they see (saw?) some value in being known as Trump's host... but not that much value
Same reason why banks keep loaning Trump companies when they default over and over again and why lawyers keep working for Trump when he refuses to pay them.
They think the cache of being associated with Trump will have some future benefit. They have been wrong for 40 years.
