Issue arose that would affect audit tracking but team and PO made decision to go ahead with release. Although we have not had extent of testing previously hoped for due to fact release will be easy to roll back team and stakeholders decided risk is minimal. Still a go for Thursday. Issues seem to be environmental ie load balance and db connectivity, possible data not assumed to be an issue with code packaged in release. 4/29/2010 17 Release 1.7.1 went live this morning and no issues were raised in deployment post verification checks all passed. Team went upstairs and spoke with editors to see impact and if performance improved. Noticed that client machines used by editors were extremely slow. Team will spend two days stablising live and problem solving. Known issues exist with networks and methode 4 (our key dependency and target of most implemented change in interface). Team and methode 4 representatives have meeting to resolve any possible issues. Client performance still deemed unacceptable. Methode was upgraded to version 4 previous to our release and performance degradation had been noticied prior to our release. Hawks all day resolving live issues. 4/30/2010 18 Today whole team are working on live defects raised relating to performance that has been considered to have been incurred following release 1.7 which went live on Saturday 24 April. 1.7.1 went live on Thursday 29th of April and does not seem to have made matters worse but in fact resulted in mild performance improvement. MW and NG are going upstairs to sit with users and try to capture specifics as to when issues are encountered they will be comparing performance inside m4 client and ie7. DS looked at a registry setting to improve javascript performance but this was not a workable solution. Team will be compiling a comprehensive list of users will speak with MS and BM to do this RH may also be able to help compile this. GJ CR and Ian pleasance attended they will be taking a look at any environment issues that may be having an affect. RH is performing snoop tests to help ascertain if any data issues may be having performance impact. AF dialled in and had spoken with BM raised the option of rolling back but team and CR believe this is too high risk and may result in system failure. Editorial are concerned that election week is next week so do not want multiple small changes 5/1/2010 19 Weekend 5/2/2010 20 Weekend 5/3/2010 21 Early spring bank holiday entire team on leave. 5/4/2010 22 Based upon the activity on Friday where team analyzed live issues following the release of 1.7 new actions were taken. The team de-scoped some of the issues from their inventory and used these as lessons learnt exercise. Most of these issues raised pointed to methode 4 user experience issues and caching. A new technical task was created to produce a server side script to ensure that cache items a kept alive by polling the relevant pages every 20 mins or so. JDC and NG are implementing this. Other technical tasks were raised to understand and resolve why site performance degrades somewhere between 2300hrs to 0100hrs (current assumption is mysql backup job running) and to apply additional logging to server side activities that would have been helpful while trying to analyze current problems but were not available.Friday, 1 April 2011 Editorial product support were informed that we are available on call today to respond to issues team have been provided
