I've been a customer of this company's for over 15 years, and until recently I've been for the most part entirely satisfied. Recently however I've been encountering radically degraded service often marked by repeated unkept promises to call back or to fix. (The promises to call back are upon my request quite specific [as: by 4pm]--but they're simply ignored.) Examples follow: (a) Some time ago the company changed its server/Web mail to Zimbra. Amazingly, a given Zimbra filter will work only sometimes. (b) The company also uses the blocking services of an outfit called Redcondor, which unaccountably will block *my own* outgoing messages, without my knowledge. (c) Although Redcondor allows me to whitelist sending domains and URLs, it will not honor my whitelist! (d) My Internet service has been for the last two weeks or more erratic, in that I will repeatedly get a "server not found" error (for all websites). If I keep trying I will eventually get service, but in the meantime I can't use the Internet. I can't currently recommend DSL Extreme for anyone. I myself will be leaving as soon as a find a replacement.
