The sea level is certainly rising, but post-glacial rebound is also bending
the entire East Coast of the United States, which means that parts of the
East Coast are sinking into rising oceans.
Unfortunately, that includes the New York city area in the downwards zone.
Note that most of the intrinsic sea level change is due to the thermal
expansion of upper ocean layers, and that can vary regionally, and
this regional variation appears to be driving some of what we see.
The sea level in Southern Florida is persistently rising even though it's
not entirely clear why (if I had to bet, I'd bet on post-glacial rebound).
Florida sits on very water permeable rock and I would thus worry the most
about the Internet infrastructure in Southern Florida, but I suspect anyone
there already knows about this.
