Since July 17 secure web sites work very slowly on TOT ADSL connection. Looks like the problem is Thailand-wide:

It is definitely not blocking, but perhaps traffic shaping gone wrong? We noticed all the other sites are loading a lot slower, and HTTPS protocol is very sensitive to the packet loss…

The customer was issued the following hardware for the TOT Fiber optic 10Mbps home package:

Fiber: single fiber, dual wavelength with an SC connector.

Optical Network Unit (ONU): Mitsubishi AS-1000GN2-1GC.

Router: Welltech Computer WG-332S (not even listed on Welltech website). I think I never saw the router without any authentication before! It is a VoIP router with two FXS ports, also one LAN port is labelled (by TOT) as IPTV.

We took the Welltech router out and set up a PPPoE connection from Ubuntu Linux server through Mitsubishi modem.

Getting a lot of these errors today, looks like the connections limit is too low on TOT server?

With several customers we are experiencing a problem when email sent to the same address as From: address through smtp.totisp.net (currently resolving to 118.175.8.10) never makes it to the destination. No errors are reported. One of these customers has both TOT and TT&T ADSL lines; sending through TT&T SMTP works and sending through TOT SMTP does not. We would like to hear from people who experience the same problem.
