if you are "lagging" off it may be your ISP that blows, not DALnet.
Like others posting to this thread i use dalenet on a regular basis and though there have been days that connecting was an issue, there is nothing happening on dalnet that I haven't had happen on any other net.
things to consider: is your ISP a [CENSORED] piece of [CENSORED] that is having packet loss issues or just plain blows?
are you using the right port (or did you even try other ports?)
did you consider it might be a short term problem?
