I have noticed hit or miss (mostly miss) slowness accessing the NGA Sempervivum and Jovibarba Forum all day today and tonight (07/28/2018). I have verified the internet performance is okay on other sites and various browsers, but keep getting time-outs with NGA. Does anyone know of they are doing maintenance of the database today gthat could account for the slowness?

I haven't had any problems today Mark. Post here to see if it is something with your browser.

It's been normal for me today, Mark.

Thanks for reporting in. The site is working fine today, yesterday it was intermittently stalling, inability to hit many pages or post messages, and giving time-out messages etc., most likely something along the internet gateway routing to the NGA server location was down or being re-routed across country causing delays when hitting the site from the East Coast. By the way, where are the NGA database servers hosted, I'm assuming California?

Texas.
