[Skunkworks] Zuku and WHM/cPanel Access

Hi All, Anyone else having problems with very slow loads or failures when trying to access your WHM/cPanel accounts on SSL? I've been having this problem on both my Zuku accounts but when I switch to Safaricom modem, super-fast and without any issues, just happening on Zuku. Be interesting to know if anyone else is having the same issue. Regards Sham
