I suffered it for quite while on my BT Infinity connection: With regular spikes
It did not seem to harm the connection and if I timed a massive download to co-incide the data rate did not vary.
Then, after a difficult to resolve fault was sorted the spikes disappeared: The day the fault was resolved
And as of now a typical day will be: No spikes!
During the fault resolution we tried different modems, but they were not the issue, and noticed that the ECI gave a better throughput so I have that installed in place of the Huawei. If I put the Huawei back, the spikes return.
