Yes, Sarah, it seems to be working now, but the problem (which has been chronic for some 9 months) is that in 5 min from now it could be unusable.
Some of us use it as a tool, and we (the people who supply and manage the data without which the Gateway would not exist) need access when we are carrying out particular and sometimes quite urgent tasks.
You would not tolerate a situation where you never knew if your car would start to get you to the station in time, or if it got you a mile down the road it would suddenly decide only to run in second gear, or just stop for a random period. What we need is a fix, and your post of 2 August has left some of your greatest supporters (they include me) on the edge of despair.
