Comcast contact for wholesale ethernet/local loop
by TJ Trout 06 Mar '19

Does anyone know the name, or have contact information for the department within Comcast that handles carriers looking to purchase local access, etc? Normally this would be the carrier or wholesale group, but either of their websites seem to be aligned to the services we are looking for? Thank you, TJ Trout EXPOHL LLC AS62809

Re: How to choose a transit provider?

Is this really true in the general case? Adding colo and IX to transport and transit involves at least one additional cross connect and an IX port fee. This is likely to push the total above the pure DIA price. However, regardless of how the numbers pencil out, this isn't really a fair comparison. For small ISPs, the yardstick against which adding an IX to the mix is usually measured against is the marginal cost of IP transit. Given that the cost of transport is fixed, is it more economical to buy more IP transit or to join an IX? Transit being so cheap means that joining an IX isn't always so enticing from a financial perspective, although there are other non-monetary benefits. I certainly subscribe to the notion that transport + transit is usually less expensive than DIA, but this does depend on the market and location. Jared

Afternoon, I have searched the forums and have had no luck. We have just received a new block of ip's. None of my subscribers can get to Hulu. I have started updating all the major GeoIP Databases. I figure I need to get Hulu to update their database. Of course calling regular support is useless Anyone have a contact? John Alcock john(a)alcock.org Network Engineer Highland Communications

AT&T or Cogent Assistance

Good Evening, Can anyone from AT&T or Cogent assist me? I cannot connect between two of my sites, and the issue appears to be either on AT&T’s network or between AT&T and Cogent according to traceroute.

Question about ISP billing procedures
by Daniel Rohan 02 Mar '19

02 Mar '19

Can anyone shed light on how ISPs handle missing samples when calculating p95s for monthly billing cycles? Do they fill null samples with zeros or leave them as null? I’m working on a billing sanity tool and want to make sure to cover my corner cases well. Thanks! Dan -- Thanks, Dan
