Yes due to the outage in Whitehaven, which was the OPs original question. I finally got through to customer service and the fix date is the 10/2 (information for the OP). I am just trying to help.
Not really relevant to the OP. The issue is a service outage in Whitehaven. The OP was asking if anyone else was having issues not whether Smarty is suitable for broadband.
Same here. I use it for broadband in my flat and reception is appalling. I've tried to contact Smarty but a waste of time on their chat. No response. Seemingly EE having similar issues.
