Are these issues Spark had today ongoing problems?

I have vdsl and static IP, and internet has been out for much of the day.  Only having come back on in the last hour.

However we have been having frequent internet dropouts last couple of weeks, most days in fact. for usually an hour or more at a time, notably was dead when I got up to watch the ABs play (on sky) and didn't come back till after the final whistle...

Basically modem shows connected, but no pages load, tried other computers, all the same.  Restarted, factory reset modem last week, still the same.  Modem is only a few months old, Netcom NF4V.  

Had a similar experience some time back from an apparent DOS attack, which was assisted in this forum, and resolved by changing the IP.  This feels very similar but I do not have the same excessively large data usage s this time (other than my own). 

Rang and booked call back with technical support which duly arrived after hour and a half, only to be transferred through, then silence then disconnected.  Not real impressed...
