Cannot connect to www.ehosting.com

[#1]

Hi All,
Not sure if this is PluNet related, or BT routing issues, or what else.  I have a number of websites hosted on www.ehosting.com and have not been able to connect to them via ftp or http since lunchtime.  There is urgent work that must take place before clients login tomorrow morning.  What am I to do?!
I rebooted the router in an effort to flush the DNS cache and have now managed to connect, albeit at less that dialup speeds (it takes minutes for pages to load and half the CSS won't load).
I can see that I am using:

Primary DNS Server	  212.159.6.9 
Secondary DNS Server	212.159.6.10

I have raised a ticket hoping that PN can resolve this before too long.  Is there anything else I can do?

I've tried to connect and it is flakey at best.
Out of 3 attempts to get a web page I have managed once and that was a mangled page.
I don't think it is your connection more an issue with ehosting.com

I could not even resolve `ehosting.com`

Thanks guys,
I also raised a ticket with ehosting.com and they say they can't see anything wrong with their network . . .

I've managed to get a tracert

However, loading pages runs like a pig and when I try to use e.g. the control panel it completely zonks out.

Seems to be behaving itself a bit more.

Could it all have to do with contention across the Internet . . . ? 
I can login normally now, after more than 10 hours of frustration!
Thanks guys.
