TWTC apparently gold-plates their networks.

Thanks for the info. The City of Fredericksburg runs on TWC, and I can get a trace etc. from any number of local coffee shops, nearly all of which run off of (shh, residential) TWC. Not terribly enthused about using the same network that powers cable customers around here, but if the prices they're quoting me are legit then there really is no better option.
Is this Time Warner Cable or Time Warner Telecom? The networks are a bit different.

Here the AS-PATH shouldn't be too bad; RR-Austin/SA/Houston out to Adelphia/L3. For IPs I'll make sure to look into ARIN ASAP; want to streamline things as much as possible and going through TWC for IPs doesn't sound like the way to do that.

Will have to talk to the TWC fiber custs around here to see what kind of service they're getting. I've heard of outages before, but I'm also thinking of doing some sort of failover/low-weight BGP with another provider (which will be more expensive) to make my service more reliable than their system alone.
Getting two providers would be a good idea. Get a t1 or 2xt1 and do bgp load balancing / failover with it so then if your twc connection went down at least you would have something.

I am not sure how many ip addresses you have now, but getting them from arin isnt too bad. We where able to get a /22 just by showing them around a /23's worth of ip addresses that where swip'd to us.]]> http://www.dslreports.com/forum/remark,22468105 Sat, 30 May 2009 08:23:40 EDT Re: TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22467303 iansltx : Here the AS-PATH shouldn't be too bad; RR-Austin/SA/Houston out to Adelphia/L3.

My issue is I have to prepend my AS 2-3 times on it to balance out my Cogent link. It isn't a huge deal, just something to be aware of if your other provider has very aggressive peering.

My AS-path is 20231 (RR WI) to 11955 (RR Kansas City) -> Adelphia/Level3.

As a ISP we haven't had any competitive issues from using TWC. This might be a region-specific thing, but our local TWC people have been fantastic. Now, only 2% or so of our area overlaps with TWC so that might be part of it.
Our local TWC is trying to grow their MetroE based business like mad.

The local business support people are pretty good. If there is a issues they call us about the same time Nagios pages me, within 5 minutes.
For any BGP issues their support people punt to their network engineers. Their network engineers are great. On the rare occasion that we have a routing issue problem I can call up one of their network engineers directly and work it out.

One potential gotcha. We asked for a /24 from them for scratch space and apparently their IP allocations are controlled by a group out east. This group is hostile to ISPs. They wanted full customer info for each IP. If you have ARIN space this won't be a big deal.]]> http://www.dslreports.com/forum/remark,22467133 Fri, 29 May 2009 23:11:01 EDT Re: TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22460165 iansltx : Fair enough. Though around here local peering isn't horrible...it's just in Houston, several ms away. Woul prefer Dallas but you take what you can get. Since it's a total TWC loop sounds like I shouldn't have too many/any problems.

Just curious about the BGP part though; I see RR-RC everywhere and am wondering how different/screwy it is vs. other BGP. Is it because you're an RR-RC, then you connect to TWC's network which is also an RR-RC, which then connects to ADELPHIA-AS most of the time?

Thanks for the info! Though I'm a bit iffy about getting my backbone primarily (and it would be primarily due to the large cost delta) from a potential competitor (by potential I mean if I served any customer in town it'd be at the expense of that customer being a TWC subscriber).]]> http://www.dslreports.com/forum/remark,22460165 Thu, 28 May 2009 19:01:18 EDT Re: TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22458963 ar32h : We use TWC in Wisconsin for multiple GigE links and DIA.

So long as the point-to-point runs are on TWC's network we haven't had any problems.
We have one that crosses over into Charter half way and have frequent outages (within planned maintenance windows but still) due to work at their cross-connect location.

TWC's DIA is fine except for the screwy way they set up their BGP. In our neck of the woods you have to jump through three TWC ASs before you branch to other providers. Makes the BGP weighting a bit messy.
If they are your only provider and you don't care a lot about local peering they should be fine.]]> http://www.dslreports.com/forum/remark,22458963 Thu, 28 May 2009 15:37:24 EDT Re: TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22458799 iansltx : Of course I woudln't be sharing with them directly; coax is per-node sharing and I'd only be using the same backhaul lines as them to hte internet. Which are, hopefully (they've gotta be) plenty...]]> http://www.dslreports.com/forum/remark,22458799 Thu, 28 May 2009 15:06:58 EDT Re: TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22457986 JoelC707 :

With the fiber connection you arent going to be sharing it with anyone on a local level, the only possible sharing point would be at a backhauling/transit level and with the amount of customers and traffic they have in the area im sure you will be fine.
Correct. Actually that's the only point you can be guaranteed to be sharing with other users. Don't worry about "sharing with cable modem users", you won't be. At least not in any sense that you would notice them.]]> http://www.dslreports.com/forum/remark,22457986 Thu, 28 May 2009 12:46:47 EDT Re: TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22455873 iansltx : The note about their backbone in this area is encouraging. They seem to have a generous helping of L3, whose network I like.

I suppose I trust rDNS on traceroutes a bit too much...seeing "ge" in there made me a bit queasy, but then again all of Kerrville's bandwidth goes over an OC3 from what I hear (from ATT).

Here in Fredericksburg, according to folks at the city level, TWC was basically the savior for communications by buying out TCI Cable, which was doing such a crappy job in the nineties that the city was going to work with Kerrville Telephone Company to overbuild TCI's network with their own HFC system.

Verizon at the time only had T1 service and it was freaskishly expensive to do loops connecting city offices, schools, etc. so the city had to build out its own dark fiber for that purpose. To this day, Verizon still has no DSL (et alone FiOS) and it seems anything above bonded T1s are hard to come by.

So, as the city was working to get serviceable TV and broadband to TCIers, TWC came in, bought the TCI system and upgraded everything. The system is beginning to show its age again (easy to do when you're selling 15/2 packages over DOCSIS 1.1) but the city's connection to the internet is via TWC.

Side note: I'll respond to your IM in a sec. Looks like big city pricing is, as usual, a heckuva lot cheaper than out here.]]> http://www.dslreports.com/forum/remark,22455873 Thu, 28 May 2009 00:20:16 EDT Re: TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22455328 cooldude9919 : I dont know what kind of bandwidth they have running into Fredericksburg, if its their own fiber backhauling to san antontio or austin, or something else, but i would guess its enough. In the city directly i know they have plenty of bandwidth, in the neighborhood of many 10gb waves going to houston i believe before dumping out on the internet. With the fiber connection you arent going to be sharing it with anyone on a local level, the only possible sharing point would be at a backhauling/transit level and with the amount of customers and traffic they have in the area im sure you will be fine.

The only thing i could find that was close was the ethernet offering from XO communications which is baiscally just bonded copper dsl lines and it maxes out at 10mbit and you have to be pretty close to a central office. With the option to upgrade the fiber speed easily at any time, xo's offering really didnt compare.

We have some other twc sites throughout the country and some charter fiber sites, and i can honestly say the twc network/backbone in the austin and san antonio area is better than any other sites ive seen.]]> http://www.dslreports.com/forum/remark,22455328 Wed, 27 May 2009 22:26:13 EDT Re: TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22455259 iansltx : Thanks for the info.

If you are interested in any trace routes or anything like that let me know, as your service would head to one of those cities before heading over to houston.

As for the service it works great and i havent had any real problems. Expect construction to take 90-120 days. Most we have paid for construction is $1000 and the rest they role into the MRC. I always normally start first with the site survery to see what my real cost is going to be, so i would get that done to see where you stand. You could have no upfront cost, or have to pay $20k, it just depends how close your site is to a fiber splice point, if you have existing conduit in the building and your contract term (we normally do 3 or 5 years)

If you have any other questions let me know.]]> http://www.dslreports.com/forum/remark,22455225 Wed, 27 May 2009 22:11:24 EDT TWC Fiber - Any Experience? http://www.dslreports.com/forum/remark,22453380 iansltx : Just got quotes back from Time Warner for their fiber product. I'm not terribly enthused with their backbone network, but the pricing at a 10M commit per Mbit is comparable to per-Mbit on a Ds3 from Qwest at my location.

I was made quite aware that the MRC would be in addition to installation charges, TBD after a site survey, but paying about the same for 10Mbit as I'd be paying for 3 Mbit elsewhere is nothing to sneeze at.

So what have you guys' experiences with TWC been on their fiber products?]]> http://www.dslreports.com/forum/remark,22453380 Wed, 27 May 2009 17:03:52 EDT
