Please answer my questions, I want to buy internet service from you!

I'm sending these emails out to internet providers in Florida.  AT&T is one of them, but they don't seem to have an email address.  Also, on the question asking for an email address, the account that said to PM them instead seems to now have PMs disabled: https://forums.att.com/t5/Wireless-Account/Email-address-for-AT-amp-T-Customer-Service-Satisfaction/td-p/4821368

So, I'm posting the questions here.  Maybe others will find the answers to these questions useful, and others can feel free to chime in with more questions.  Thanks to the AT&T employee who answers all my questions!

I'm currently relocating to Florida and am partially deciding where to go
based upon the availability of good internet service. As such, I have
questions about your service, some of which are quite technical. Feel
free to reply with answers to the questions you can answer now, and get
back to me with the other answers later if you don't have all of the
information on hand.

1) What services do you offer, and where do you offer them? Maybe you
have a service map you could send me?

2) What last mile technologies are you using and where? e.g. VDSL2
Profile 17a, DOCSIS 3.1, etc.

3) What connection speeds are you offering? Is the speed symmetric? If
asymmetric, can I trade some down speed for up speed? (For example, if you
offered 100 Mbit/s down with 10 Mbit/s up, I would be happy to trade half
my down speed for half of the traded up speed i.e. 100/10 becomes 50/35)

4) Do you provide the on premises equipment or am I responsible for
providing it?

5) If you provide the on premises equipment, is it capable of operating in
a transparent mode? (Does it take the packet from the ethernet and put
it on your transport medium and vice-versa without mangling the packets in
any way? No NAT, for example.) This mode of operation is sometimes called
bridged mode.

6) Do you provide one or more public IPv4 addresses? Do they change? If
so, how often do they change?

7) Do you provide one or more public IPv6 addresses? Do you advertise
them? Do you require that I use DHCPv6? Do they change? If so, how often
do they change?

😎 How much does your service cost? What is the base rate? What is the
total cost including, but not limited to, regulatory fees, taxes,
and equipment rental fees? Please note that I'm not particularly
interested in services beyond fixed internet service. (e.g. television,
phone, or mobile service)

9) Do you preform any speed limiting, or do you allow the connection to
operate at whatever speed is available at the last mile? Is the speed
commonly limited by network congestion within or at the ingress and egress
points of your network?

10) Do you have any usage limits? Can I send and receive as much data as
I can with no change in service, or will I get cut off, slowed down,
charged more, or something else after transferring a certain amount of
data? If there are changes at different amounts of data, what are they
and at what amounts of data do they occur?

11) If you do have any limits as per question 10, how is the amount of data
calculated? e.g. Is it calculated at layer 2? Layer 3? Are headers
included or is it only the payload? Do you count data that doesn't leave
your network? (For example, a friend was hit by the bug fixed here:
https://git.openwrt.org/?p=project/odhcp6c.git;a=commit;h=5b98f902f616bd9b96a2128587bc6995555a43c1
which would cause odhcp6c to flood out link local IPv6 packets after
about 50 days due to an integer overflow. He was on Cox at the time and
they did not offer IPv6 service. Even though the packets were link local,
thus they do not, by definition, get routed anywhere, and the provider
didn't even offer IPv6 service, they still dinged him for exceeding his
usage cap.)

12) Do you zero rate any traffic? If so, what traffic? (Please be
specific, IP ranges, port numbers, protocols, etc.)

13) Do you throttle, shape, or otherwise prioritize or deprioritize any
traffic? (Again, please be specific, IP ranges, port numbers, protocols,
etc.)

14) Do you block any incoming or outgoing traffic? (e.g. can I receive
incoming TCP connections on port 25? UDP packets on port 53? Can I
initiate outgoing TCP connections to *any* host on port 25? send UDP
packets to *any* host on port 53?)

15) Do you redirect/hijack any traffic? (e.g. Redirect outgoing TCP
connections on port 25 to your own SMTP server, redirect UDP packets on
port 53 to your own DNS server?)

16) Do your DNS servers faithfully follow the DNS specifications? (e.g. Do
they respect the indicated TTL when caching records? Do they return a
record when the query should result in an NXDOMAIN return? (I can't
believe I have to ask this one, but some providers do return an address
to a web server to try and show you ads when you should have gotten an
NXDOMAIN response.))

17) Do you perform any higher level filtering or mangling? (e.g. Do you
block certain protocols? Do you block access to certain services or
websites? Do you block DNS requests or results containing certain names
or other data? Do you modify the results of HTTP or DNS requests? (I
can't believe I have to ask this one, but some providers do things like
modifying the pages returned by HTTP requests to insert their own
advertising or tracking.))

18) Do you log any traffic? If so, what do you log? How long do you keep
logs? What is your policy on providing logs to 3rd parties? Which
policies apply to which 3rd parties? What happens to the data if the ISP
is sold, merged, transferred, entered into receivership, etc? What do you
do to protect the data you log? (e.g. keep it offline, encrypt it with a
key that is not on a computer connected to the internet, encrypt it with a
key stored in a smart card or other hardware token) Can I opt out of any
logging? How will you notify me if the policy changes? Will I have an
opportunity to request that you purge all of my information before any
policy changes take effect? Will that request be granted? Will you pay
me for the use of my personal information? Will you purge any data
collected on me when I no longer pay for your service? Will you notify me
before any of my information is given to a 3rd party? Will you give me an
opportunity to decline that 3rd party have access to my information? Will
you notify me whenever any of my information has been given to a 3rd
party?

19) Do you sell your service monthly? Do I need to enter into an extended
contract? (e.g. 1 year of service) Under what circumstances can I end the
contract? (e.g. the quality of service has degraded, you decided to block
more ports, you've decided to change the terms of the contract, etc.)

20) What is your acceptable use policy?

21) Are you open to providing service via an unorthodox last mile
connection? (e.g. Service isn't technically available at my location, but
I have line of site to your head end / CO / equipment cabinet / etc and I
provide point to point laser or radio link equipment, would you be willing
to colocate one end?)

22) What access do I have to diagnostic information about my connection?
(e.g. My last provider provided equipment that actually showed a live
graph of signal to noise ratio in both directions across the available
spectrum. However, one of my past providers provided equipment which
exposed diagnostic information via SNMP, however they intentionally
disabled SNMP access for some reason and told me to call into customer
support and ask for signal strength information over the phone.)

I understand that many of these questions are very technical, but your answers will help me decide which is the company most deserving of my business.  Hopefully it can be you!
