Sounds like a routing problem of sorts to me, apache ( afaik ) has no |
| 35 |
impact on /ping/ times. My favourite tool for finding traffic problems |
| 36 |
is "mtr" , see packet loss and route and where packet loss is occuring |
| 37 |
all at once :) Sometimes it will report 100% packet loss on a middle |
| 38 |
step if that server ignores pings tho, .. .so... |
| 39 |
|
| 40 |
does curl respond properly? , or does it just sit there waiting for response? |
