Hurricane Maria: Dominica complete communication outage 12 hours
by Sean Donelan 20 Sep '17

20 Sep '17

Its very unusual to loose all communications with a country for almost 12 hours in 2017. During Hurricane Maria, essentially all communications were cut with the Commonwealth of Dominica at about September 19, 2017 at 4:00am local time. It took nearly 12 hours to re-establish any communications with officials on the island via radio. There has been some unofficial communications with ham radio operators, assumed to be on the island. All power, wireline, internet and cell service appears to still be out. Its unclear how much is due to general damage which will take a while to repair or specific points which could be repaired quickly. There are some VSAT links in Dominica, but I didn't get responses from the ones I tried. Initial aerial fly-overs by CDEMA/RSS, a joint disaster agency by 6 participating countries in the Eastern Caribbean, saw 70%-80% damage to buildings, the hospital and other infrastructure. The Barbados Coast Guard is sailing tonight towards Dominica trying to re-establish better communications for relief efforts. Additional relief personnel are due to be sent in the morning, during daylight hours.

IOS new versions and network load
by Jean-Francois Mezei 20 Sep '17

20 Sep '17

A couple years ago, Apple unleashed an IOS update which made the news because network operators reported serious congestion on their networks as everyone and their uncle tried to download the gig+ package at 11:00 PDT. Was the problem solved simply by Apple staggering the announcement of downloads? or were there distribution network changes also made to reduce the load? In Canada, during net neutralirty hearings, it was revealed that cellular carriers zero rated over the air updates. I know my iPhone gets updates without me asking for them, only getting a "update ready to install" while on a long cycling ride (aka: must have used cellular data). Does anyone know whether this is pushed by Apple who has gotten the OK form individual carriers, or is it pushed by carriers (with Apple's OK) in a low priorioty stream that doesn't cause congestion on cellular network? (carriers delivering content in "push mode" would change their role).

Level 3 SIP trunking and E911
by Christopher J. Wolff 20 Sep '17

20 Sep '17

I've been informed by my Level 3 sales rep that the only way to make moves/adds/changes for Level 3 E911 is through the portal. This seems awkward since I have Emergency Responder which can link into products like Intrado. Are there any SIP/E911 folks from Level 3 that can clarify what my options are? It would be appreciated. Thanks in advance, CJ

Dear all, Adam Chappell created an interesting shim to improve the default behaviour related to EBGP Internet routing on Juniper Junos. https://twitter.com/packetsource/status/910219911150080007 SLAX script here: https://github.com/packetsource/rfc8212-junos Props to both Adam for creating the script and to Juniper for allowing such permissionless patching! This is cool. Kind regards, Job

100G QSFP28 DAC cables - experience
by Jiri Prochazka 18 Sep '17

18 Sep '17

Hi folks, I'm wondering if anyone have (either positive or negative) experience with 100G QSFP28 DAC cables? Is there anyone who is using 100G DAC in large scale and would recommend it (which means there are no issues compared to SR4 links)? I'm thinking about cables with lenght up to 1m, not more. We have had quite bad experience with 10G DAC in the past - but I do not want to be slave of the past. Thank you for your thoughts! Jiri

Hurricane Maria: U.S. Virgin Islands suspends recovery efforts
by Sean Donelan 18 Sep '17

18 Sep '17

U.S. Virigin Islands suspended hurricane recovery efforts on the islands in order to prepare for potential landfall by Hurricane Maria on Tuesday night/Wednesday morning. Hurricane Maria is expected to strengthen to a major hurricane by Monday evening. Storm preparation efforts on the U.S. VI are being shifted to readying shelters and distributing as much food and water to people in advance of the storm. The U.S. VI Governor is warning people most of the temporary repairs from the last hurricane will be knocked out again when Hurricane Maria strikes the islands. Hurricane Maria will also impact other leeward islands beginning Monday, including Guadeloupe, Dominica, St. Kitts, Nevis, and Montserrat, and Martinique.

Re: USA local SIM card

Sounds like you should go the mvno or twilio route. Twilio is beta testing cloud based since assignments that tie into their data and SIP services. If you go the direct carrier route try mvno.

Is 3G coverage good enough in New > York and Orlando for VoIP calls (SIP, Viber, Skype)? 3G coverage is a superset of LTE coverage. (aka: carriers still have some areas that have 3G but not LTE). AT&T has 850 and 1900 in 3G. the AWS (1700/2100) is for LTE only. AT&T has shutdown 2G, but T-Mobile still has it. In Canada, Rogers still has 2G, but Bell/Telus never had 2G. (they went from CDMA to 3G circa 2010). T-Mobile does not have 850. It has AWS (1700/2100) and 1900 in the above list. Originally, it had 1900 only (2G). When it acquired 1700, it deployed 3G on it. But because the big US carriers deemed 1700 to be for LTE once it arrived, very few handset manufacturers provided support for 3G on 1700, especially during the days when handsets coudl only support 3 or 4 frequencies. Many of the hansets custom ordered by T-Mobile and the 3 small new Canadian carriers replaced 1900 support in 3G with 1700 support. (so when Rogers got the Mobilicity customers, many of them had handsets that could not support 3G services in 1900 so Rogers had to get a package to upgrade those customers). T-Mobile has subsequently refarmed 1700 to support LTE, and split its 1900 to support 2G and 3G. It has since acquired some 700 for LTE service, but this is no help to you. However, as a 3G-only user on t-mobile, you are limited to 1900 which has shorter propagation from antennas. So consider that the T-Mobile coverage maps may be built with 700mhz propagation in mind, so you would not get as much coverage on a 1900 only sertvice. There may still be areas where 3G is on 1700, but propagation is similar to 1900. (assuming your handset can support 3G on AWS (1700/2100). Note that AWS (1700/2100) is not used outside North America, even if frequemncies such as 2100 are. Carefully check your handset's specs. > 2. Is there public or private IP address? IPv6? I can't answer this. During my bike trip, I choose AT&T because it is the service which cuases me the least amount of waiting to post a tweet or check emails. Getting the IP address on an iPhone isn't easy so I didn't waste any time doing this.

Hi We are a medium ISP. We are looking for Management software solutions. We are interested in finding a solution for billing, invoicing, scheduling, ticketing, provisioning and monitoring, Any suggestions or recommendations will be appreciated? We have been using multiple systems which do not communicate. Our objective is to use a single system or at least reduce the number of systems. Thank you KARIM M.
