I've been running my own server(with help) for 7 years now. Mostly things have been very smooth

Running fedora 14
multiple virtual servers DNS/ Mail / web Hosts

Suddenly things will all the sudden not connect. Things were fast 10 seconds earlier ...and 30 seconds later things are okay again.
So I putty in to look around, putty session knocks me off after 1 minute to 5 minutes. Never seen this kind of issue before.
Uptime shows 0.15 ....or similar low load indicators.
here is the exact output:
[root@webserver1 home]# uptime
21:17:59 up 2 days, 9:03, 2 users, load average: 0.14, 0.19, 0.22


Same symptoms on DNS server / Mail Server and HTTP server. PUtty drops on all of them.

I'm at a loss on what to look for since it's intermittent. I even thought it might be my laptop running Win 10 so I try a different laptop and saw the same issue.

Another tidbit, when on in putty, the response is molasis slow. Type a command and it never keeps up. Vi a file and session will die in the middle of it. Trying to add a couple new domains and it's a nightmare to get anything done.

Very frustrating. Any ideas what to look for once I do connect? Everything has run so smoothly I've forgotten way more than I should have.

More to confuse or help the issue. If I open a putty session and let it sit, the session lasts ..at least more than 5 minutes. Also due to frustration of not being able to complete the edit of the httpd.conf file I was able to use winscp to download the file edit as needed and upload the file. No connectivity issues. from there I needed to ck permissions on a new dir I had created and winscp worked like a charm. Did not drop the connection. A putty connection also lasted during the same time frame. If I lost putty maybe the scp connection would drop also.

appears to be network issue ...still trying to get to bottom of it. any input appreaciated:
