Seacue,I've had a similar experience.For some unknown reason there was 1 site only that I was buying fibre equipment from that I couldn't access when using my DSL modem.I tried everything to no avail.I did a tracert a few times and it timed out in LA for no apparent reason after 8 hops.After 2 years,with nothing changed at my end I can now access it fine.No-one else had any problems with the site,just me.
