After noticing severe packet loss on Friday night we have introduced an anti-loss tool. The tool works by reducing the maximum rate limit when capacity hits a certain point and then allows it back up slowly if the capacity returns. [ .. ] The variation in limits are applied on a per central basis so that if only one has a problem then only it has its limits adjusted. Users will be able to switch centrals and the limit will be reset to that of the central they reconnect to.

The rate limit changes only happen once the 5 minute average usage for that central hits 96%, once this occurs then the maximum rate limit is reduced by 500kbps. [.. ] One minute later the next 5 minute average is calculated, if usage remains above 96% then a further 500kbps will taken from the maximum limit and this will continue to a minimum of 2Mbps. [..] Once usage fall below 91% then the rate limit is raised by 200kbps. If the capacity hovers between 91% and 96% then the limit will continue at its current setting.
