Spoke with someone on IRC about this and here is what I got.
I can confirm this is on your ISP's side. It appears as if several ISPs are taking over irc.deltaanime.net for their own malicious reasons
Likely we've been added to a blacklist of sorts. We are investigating the issue, but can confirm that it is ISP-side. You should be able to connect through irc.frantech.ca in the interm.
I am able to connect to irc.frantech.ca but shortly after I get
* [10053] Software caused connection abort
One step closer to being able to get on mirc and yes I am aware that 10053 is a general error.
That error is one of the most common, and sadly, one of the least informative in terms of fixing it.
