My connection has been slow everywhere today. I thought maybe it was Cyber Monday shopping issue related
We've had a tube strike here in London and today was nicknamed "stay at home Monday". That no doubt made it slower locally, and I would guess that a lot of the rest of the country stayed at home due to the February weather we have had of late.
The server we reside on is the nuts nowadays and we will still get slow when other accounts are doing their maintenance thing, but our load rarely goes above 1 and I am hosting about 8 sites myself. That said, gremlins know no honour..
