So, my Internet will be cut off sometime tomorrow (12 March), since I cancelled the contract. And because I dragged my feet too long before getting in touch with the new ISP, I won't be getting service from them until 19 March. So, one week without Internet at home. I'll survive somehow :)
One negative side-effect is that I won't be able to IM Stella from work for that time.
And hopefully the set-up from the new provider will be painless. (I ordered their WLAN option; will see how well that works out. Supposedly, my desktop computer is WLAN capable, but I've never tried it out. Apparently it only does 2 Mbps, though.)
