With so many folk at home and using the internet, will the system cope? Or will home bandwidth struggle?
This is something of a over simplification, but broadly speaking there are two sides to this...
The link from home to website.....so this is your broadband line itself. If, like me, you pay for super fast speeds you may notice slower performance to what you are used to. This is because they will throttle your speeds and share bandwidth. Most people should be ok though.
The second part of this is site you are connecting to. This could be something like BBC News, or your own work servers that your employer uses. If there is an increase in the number of people hitting the same site, it's possible that the server itself struggles to keep up. I should imagine the BBC News website is seeing a much bigger hit right now, but they will have enough kit in place to cope. Your workplace may not though. If they are used to say, 25%, of people working from home, but now they have 80% of people working from home, then their hardware may be struggling right now. This is because when you are sitting in the office, you connect to work systems through one lot of hardware, but when connecting from home you will use different hardware to get to the system. As I said before, this remote access hardware may be being overworked, so people may find they have issues.
All-in-all, the broadband link should be ok unless you live in remote areas that already have rubbish connections.
Sites like Netflix, Amazon and BBC News should be ok as they are designed to beef themselves up during high demand.
Home shopping sites from supermarkets may be working harder than normal, but again should be ok.
Performance of your work systems will very much depend on what investment your company has made in the past.
