Further analysis of the Election period webcast ----------------------------------------------- We have now had some time to analyse log files from the election period. The following observations are made. It should be understood that there were 4 servers, USA - 1 AKL - 2 (CityLink and TVNZ) WLG - 1 We have not had access to the TVNZ log files and so the following comments are based on analysis of 3 servers only. These servers were carrying 62% of the load (by traffic) It also needs to be understood that these servers were not set up solely for the election event and carried on handling day to day 24x7 streaming. So in looking at log files, there are many streams and services (such as on demand video or audio files) which were operating regardless of the election. Equally many of the stations which we stream had no particular coverage of the election and carried on their usual Saturday night programmes. As a result some analysis requires a little local knowledge to make sense. In addition, R2 was providing on-demand services to 3 political parties involved in the election. Several parties had closing video clips or focussed their multi-media assets for the closing stages of the campaign. This produced extra traffic on election day. In some cases a surprising number of hits. We also carried a number of election related events such as The Labour Party Election Campaign launch The InternetNZ ICT Candidates debate Election Fiscal Update (access via Scooop.co.nz) Several Press Briefings by the PM (access via Scoop.co.nz) Candidate debates (access via RadioNZ.co.nz) As a result a very rough estimate is that the last month has seen server traffic double. On election night, over 40 countries accessed the 3 CityLink servers. They were NZ 36% Australia 12% US 8% UK 2.5% France 1.5% Canada Japan Netherlands Singapore Switzerland Germany Czech Republic Italy Brazil Thailand Poland Malaysia Austria Saudi Arabia Israel India Hungary Taiwan Turkey Spain Slovakia Belgium Sweden Denmark Norway Fiji Azerbaijan United Arab Emirates Russia Philippines The top 15 countries all accessed over 1GBytes of data Of great interest to us is the access to the USA server as its usage is designed to handle international interest under a strategy of locating servers as close to the clients as possible, so that over time, higher quality material (audio or video) can be delivered. The USA server received connections from NZ 30% Australia 20% USA 10% UK 3.7% Japan 1.5% Singapore 1.3% With 3 servers located in NZ, there was no need for traffic from the US server to NZ. This is caused solely by poor peering by NZ ISPs. It represents some 10Mbps of traffic.
