How many times can an internet connection interruption occur and still be considered acceptable?

Thank you, this seems to be the issue. I know that Bezeq has recently
installed (within the past year) a connection box ‏ 30 meters from my
building, with all sorts of fiber optic connections inside, buzzing fans and
blinking lights. The guy who installed it showed me around the box while
my dog waited patiently for her walk!

In fact, just last week I got a call from Bezeq offering to upgrade my 5 MiB/sec
connection to something higher that I don't remember. I refused only because
he wanted my billing information and I wasn't willing to give that
information to
someone who called _me_, rather I said that I'll call Bezeq and give that
information. When it turned out that was impossible, I decided that I
was talking
to a phone-phisher and told him that I refuse to give that information
over a call
that I did not initiate.

I don't understand why this would be an issue. Why are the routing
tables going to be larger? The router needs store only the routing
tables for the devices that it acts as a default gateway for, i.e. my
LAN and that hasn't changed. Wouldn't NAT tables be discarded anyway
after a short time? How else could two computers on the LAN browse the
same website?

I'll ask about that. Thanks.

Thank you!
