Sigh..
While that log means absolutely nothing (netsplits will, and will always happe), EFnet is sucking in the last 6 months (or more).
Why?  Mostly due to a combination of DoS, and far, far, too many admins that just stopped caring.  Efnet WILL fragment, it's just a matter of time.  It's just been sad to watch the demise of something that used to be so great.  I think the underlying cause is that it's just not fun anymore.  It used to be fun for the admins, and they got enjoyment/fulfillment from providing such a valuable service.  But then smurf (the first real DoS capable of toppling the entire networks of the IRC servers.  i.e. eating into other revenue streams) came along and things started to get un-fun as they had to defend the existance of this server that caused so many problem to their managers.  I honestly don't know how some admins can keep their servers going any longer, with te just huge amounts of DoS going against them.  It seems pretty much only massively large companies (glbx, exodus, concentric, etc.), large educational institutions, and the semi-large regional backbone providers (lightning.net, core.com, etc.) who's owners/upper level management love IRC will be the ones with the capacity to host a server any longer.
That sucks, EFnet was built on small local ISP's that had a few T1's coming in.  Sigh.
As for getting on EFnet?  Get the server admins in your back pocket. 

  I co-locate an EFnet admin's box, so we have I lines from that.  Also get a local server to add I lines for you, most will.
Ah well.. IRC will never completely die.  Too many people use it as a valuable tool for communication and just general help.
peace,
