SDossett: [snip] The main reason for my concern that the issue will not be one on site is that a friend of mine suffered from a similar fault at the same time and fixed it by changing from Spark to another service provider.
These sorts of issues are almost exclusively physical wiring issues (be it your property, or a Chorus line). Changing providers doesn't resolve these issues normally. Spark are also generally very responsive to helping resolve these sorts of problems.
Mised catching this bit.
More than likely the change of providers was pure coincidence rather than causation.
change of modem, cables, heck even just a move of the modem could also contribute.
Changing providers will often cause profiles to reset.
Typically disconnection faults last for about 3 days and self restore without anything being fixed. #ddDLM.
