Is anyone else experiencing continual drop outs with Vodafone at the moment?

At times the VDSL works fine but on a consistent basis it hangs for up to a minute.  During one of the drop offs I ran an Ookla speed test.  I was getting download and upload speeds of 0.3!

I contacted Vodafone Broadband help desk.  They said that they could not see any problem from their end.  They said they would change some settings at their end and give me a call back later in the day to see if things had improved.  As you would expect I did not receive a call nor has the problem been sorted.

I have restated the modem numerous times to no avail.

I would be interested to hear if anyone else is having this problem or any suggested fixes.  Thanks in advance.
