Reports received by Groundviews indicate that Tamilnet is inaccessible from many major Internet Service Providers (ISPs) in Sri Lanka. At the time of writing, the site is confirmed to be inaccessible from:
SLT (ADSL and dial-up)
Lankacom (leased line)
Lankabell (dial-up)
Suntel (dial-up)
Only Tamilnet seems to be affected. There is a workaround.
