Got a note from an ISP today indicating that my website

It's only the 7th day of the month and this hadn't been a
problem in the 6 years they'd hosted the service.
 Turns out that three chinese sources had downloaded the same
set of files, each 262 times. That would do it.
 So, anyone else looking to update bipolar semiconductor,
packaging or spice parameter spreadsheets; look at K.A.Pullen's
'Conductance Design Curve Manual' or any of the other bits
stored at ve3ute.ca are out of luck, for the rest of the month .
 Seems strange that the same three addresses downloaded the
same files, the same number of times. Is this a denial of
service attack?

Of sorts.
You might look at the *times* to see if it looks "mechanical"
or "human initiated".
You could change your "service" to one that delivers *requested*
content; email driven so you can insert your own metering function
in that loop.  Or, a combination of the two -- hide the content
and return a one-time, unique, time-limited URL as the result of
an *approved* email request...
[Or, you can *hide* your site and only make it available by
invitation]
