Last night saw a bit of down-time on the site as the Data Centre the Nexus server is hosted on went through an infastructure upgrade. I apologise for not informing you all sooner about the issue but there were difficulties in ascertaining which server was actually going down! However...
Many folks both here on the Nexus forums and over at the official Bethesda forums have commented recently on the site being slow during American peak hours. Unfortunately I haven't had the time to investigate this issue (i.e. stay up until 3am in the morning GMT/DST and do some investigative work server-side) due to various real-life issues. However in the hopes of actually getting some sleep on the night I am able to investigate the issue I wouldn't mind having some definitive times at which the site is down or very slow.
If anyone does know the times at which the site is unusable please post them up here so you can help me manage my sleep! Thank you.
The site is quite bloated and an explorative look through the code at bloated and inefficient features has been on the cards for a long time, as well as adding in some anti-spam features to help reduce load for legitimate users. It may be that the server configs just need a few very simple tweaks, it may be some buggy code (I'm no coding guru, that's for sure!) or it may mean the server hardware can't keep up with the demand for the site, in which case I'll have to dig into the old pockets again!
Statistically Sunday's are the busiest days of the week for the site where traffic tops 60,000 unique visitors and 525,000 page views for the day; that's 6 page requests a second! Such traffic figures have remained steady for the better part of 10 months now which just goes to show how strong the ES modding scene still is.
