Status Report All of our services have been performing very well and we have no real
problems of any type. We are constantly monitoring many aspects of the services and all are performing well.
Although our main wholesale supplier of data, EISA, has been in the news, it has not affected their
performances in any way. Also we have contingency plans in place to switch to alternate sources should
problems arise.
Many of you would have noticed the effect when we disabled the timer on Saturday 1 July and allowed unlimited access. This was done partly to give our users more for their money and partly to monitor the effects of such an offer. The result was amazing. Probably the most noticeable effect was the very poor response. This was due to the fact that our line to EISA had completely saturated by 9.00 am and stayed saturated for 16 hours, until 1.00 am on Sunday. The phone lines were saturated for about 12 hours. A few users managed to stay on for over 15 hours and many had over 10 hours. Average user time/day on line was 103 minutes (The normal figure is amazingly constant and is usually in the range 63 to 65 minutes, month after month.) The number of different users in this period was 2662. This is slightly down on an average Saturday, possibly because all the phone lines were busy. On an average weekday 3,200 different users log in. This experiment gave us a very clear indication that we cannot offer a completely unlimited time service. Inactivity Timer There is still some confusion, possibly due to lack of information, on the inactivity timer. It is used to disconnect an inactive line. Our inactivity timer is set for 20 minutes. All ISPs have an inactivity timer. This is to prevent the phone lines being tied up if someone forgets they are connected. It can happen when you close down your e-mail and forget to log off. Also you should be aware that most Web browsers have an inactivity timer that can be set by the user. It terminates the connection from the users end at their request. The maximum inactivity time would be the lesser of our timer and their own. The only real or practical disadvantage of this timer is when reading and then replying to mail. If you have decided to reply and you are typing a long letter, there will he no data being sent to or received from the server. So it's possible to be disconnected in such an event. The only solution is either to write your letter offline and then post your mail when you re-connect or have a browser open and every 15 minutes click on a link or click in the Refresh icon to create some activity.
