I am facing problems with some sites since yesterday.
some like google work fine but in between they too are off.
this is what i get when i test


oh by the way my primary is 4.2.2.1
and sec is 203.94.243.70
 
Well after using 4.2.2.1 , i did'nt notice any change. On the contraty it may have slowed my internet.I'd say stick to 203.94.243.70 as primary and 203.94.227.70 as secondary.Both the DNS are working.
 
The level3 DNS servers (4.2.2.1) are overloaded catering to its own customers let alone handle additional users. Added to that they are located in the US, geographical distance adds to the resolve time. The end result you have already felt, slower resolving.
 
^^ agreed , they are so slow i dont kno why people recommend them , using an indian dns is MUCH better , even open dns is slow for me
 
I use Airtel, Spectranet DNS on MTNL

they are open? what are IPs?
 
Spectra Net are :203.122.63.152, 203.122.63.154Airtel are :203.145.184.13202.56.250.5Airtel ones dont seem to be open Btw i use 210.7.79.193 (my isp's) and 203.94.243.70 - which has a ping of ~15 ms for me dont kno from where it came i just read it somewhere
 
Level 3's DNS are slow but they are not slower than MTNL..spectranet is best performer when it comes to indian DNSLevel-3 4. 2. 2. 1 | Min | Avg | Max |Std.Dev|Reliab%| ----------------+-------+-------+-------+-------+-------+ Cached Name | 0.242 | 0.247 | 0.266 | 0.004 | 100.0 | Uncached Name | 0.248 | 0.301 | 0.432 | 0.044 | 100.0 | DotCom Lookup | 0.252 | 3.654 | 4.516 | 1.501 | 98.6 | ----------------+-------+-------+-------+-------+-------+MTNL 203. 94.243. 70 | Min | Avg | Max |Std.Dev|Reliab%| ----------------+-------+-------+-------+-------+-------+ Cached Name | 0.016 | 0.025 | 0.036 | 0.006 | 93.8 | Uncached Name | 0.184 | 0.280 | 0.372 | 0.058 | 91.8 | DotCom Lookup | 0.194 | 3.866 | 4.380 | 1.294 | 83.9 | ----------------+-------+-------+-------+-------+-------+Spectranet 203.122. 63.152 | Min | Avg | Max |Std.Dev|Reliab%| ----------------+-------+-------+-------+-------+-------+ Cached Name | 0.034 | 0.039 | 0.042 | 0.002 | 98.6 | Uncached Name | 0.196 | 0.316 | 0.406 | 0.062 | 100.0 | DotCom Lookup | 0.116 | 0.261 | 0.394 | 0.083 | 100.0 | ----------------+-------+-------+-------+-------+-------+MTNL 203. 94.227. 70 | Min | Avg | Max |Std.Dev|Reliab%| ----------------+-------+-------+-------+-------+-------+ Cached Name | 0.168 | 0.231 | 0.290 | 0.037 | 52.8 | Uncached Name | 0.320 | 0.427 | 0.504 | 0.058 | 57.9 | DotCom Lookup | 0.328 | 0.414 | 0.474 | 0.076 | 36.4 | ----------------+-------+-------+-------+-------+-------+ Spectranet 203.122. 63.154 | Min | Avg | Max |Std.Dev|Reliab%| ----------------+-------+-------+-------+-------+-------+ Cached Name | 0.036 | 0.039 | 0.044 | 0.002 | 100.0 | Uncached Name | 0.198 | 0.317 | 0.408 | 0.059 | 100.0 | DotCom Lookup | 0.116 | 0.268 | 0.392 | 0.097 | 100.0 | ----------------+-------+-------+-------+-------+-------+
